• Added new routine Data|Sort Alphabetically. Allows you to sort rows/columns/levels of a dataset based on labels of the rows/columns/levels
• Added new function to spreadsheet editor. Under "file" in the spreadsheet menu, there is an entry called "insert columns from file". This lets you read in a new dataset and join it to the dataset you already looking at. This is handy for continually adding new variables to a dataset, say, one called "attribs".
• Added new function to matrix algebra package. Called "recode", it is used to recode values of a matrix. Syntax is as follows:
  
  -><outfile> = recode(<infile> <oldvalue> <newvalue>)
  
  for example, this changes all zeros to missing values in a dataset called campnet:
  
  ->campnet2 = recode(campnet 0 missing)

  • Implemented both a regular and sparse matrix version. They get different answers for large datasets -- presumably a rounding issue

• Replaced Tools|Scaling|Eigenvectors routine with a new one. The old would only produce first eigenvector. The new produces all, and handles non-symmetric matrices (which may result in complex eigenvalues and vectors).

• New routine under Networks|Egonets|Brokerage Elasticity. The dyadic output is meant to show what would be the effect on ego's brokerage score of adding/removing each possible tie from an ego network. Node level output shows the net effect on brokerage of each tie that was in fact added/dropped at T2

• A few fixes in Networks|Centrality|Alpha Centrality (Bonacich Power)
  • Changed "get alpha" routine to double precision to avoid rounding error
  • Added warnings when diagonal values are not constant or not zero
  • Changed the way row sums are calculated in the routine so as to include the diagonal

• Fixed bug in Networks|Egonets|Structural Holes which was causing the calculation of ego-betweenness to blow up.

• Changed the way browse buttons deliver filename. Now, if the file's filepath matches the current folder, the program presents only the filename. But if the user had browsed away from current folder, then it retains full pathname.
• Fixed bug in the writing of filenames in the logfile. It had been repeating part of the filename

• Fixed bug in Networks|Ego Networks|Structural Holes that was causing program to run out of memory with networks of around 12K nodes. Now it runs larger networks quite fast. Also fixed bug preventing egobetweenness output in the same program

• Numerous small fixes
• Changed DATA|JOIN procedure to allow resizing window and to remove distracting ".##h" from file names.
• Changed Networks|Cohesion|Reciprocity to add two new columns of measures, as well as correct the documentation printed in the log file

• Changed Networks|Cohesion|Krackhardt GTD routine so that LUB measure works with multiple components. MOre to be done here
• Added routines under Data for matching datasets via node labels. For example, if you have a network dataset and a corresponding attribute dataset, but the rows of the attribute dataset are in a different order than the rows/columns of the network dataset, you can run either Data|Match Network and Attributes or Data|Match Multiple Datasets to sort them both in the same order.
• Data|Match Multiple Datasets can also be used to sort a single dataset into alphabetical order based on node label

• Changed text area in double-dekker mrqap procedure to stop wrapping filenames
• Added ability to enter "+" in default folder field at bottom of main window to indicate your "my documents" folder. For example, if you have a folder called Data under My Documents, you could type this:

+\data

instead of having to type something like this:

C:\Documents and Settings\Username\My Documents\data

This works in Vista as well.

• Changed help viewer to html-based viewer that works with Vista.
• Fixed bug in Transform|Matrix Ops|Within Datasets|Cell Transformations that was saving the output ##d file in a different folder from the associated ##h file

• Changed algorithm used to calculate eigenvalue in the GETBETA function of Networks|Centrality|Power procedure. The old algorithm failed when a matrix had multiple eigenvalues with the same absolute value. The new algorithm always works.
• Fixed bug in Networks|Regions|K-core routine which was giving wrong values for coreness (it was delivering 1+ the correct value in most cases).

• Added feature to Networks|Egonet|Structural Holes to enable defining ego network according to incoming, outgoing or both kinds of ties. Also fixed bug causing Efficiency scores to not be missing values when degree was zero.

• Improved dialog box for selecting default folder
• Fixed bug in the way UCINET opened NetDraw

• Added procedure Networks|Ego Networks|Concentration. Given a network and a 1/0 attribute vector, the procedure calculates, for each ego, the number of pairs of alters that (a) are tied and (b) involve a given type of alter (based on the attribute vector). For example, if men are coded 1 and women 0, it measures the extent to which an ego's alters are connected to the men in the ego network
• Fixed bug in Data|Extract dialogue window which was inserting file information in the wrong edit box

• Added options to Transform|Bipartite so that row and column entity labels can be given distinctive prefixes

• Added new procedure Networks|Ego Networks|Honest Broker that computes the Kilduff and Mehra honest broker index. Essentially, an honest broker is a node who is trusted by two third parties that don't trust each other. The measure is a count of the number of pairs of alters for whom ego serves as an honest broker

• Fixed bug in the way UCINET interfaces with MAGE. Previously, there were problems when there were long filenames containing spaces

• Temporary fix made in Tools|Consensus analysis to allow calculation of probabilities of right answer in answer key when there are a large number of respondents

• Added new betweenness procedure called Proximal Betweenness. A person has high proximal betweenness if they are often the final intermediary along a short path -- in other words, a person that others receive information directly from

• Fixed bug in Transform|Matrix|Between files|Statistical summaries. When adding filenames via the browse button, long filenames were wrapping, making them impossible to read. This no longer occurs
• NOTE:  The "AVERAGE" function in Tools|Matrix Algebra as been renamed AAVG

• Changed Networks|Egonets|Egonet Strength to allow defining ego network in terms of outgoing ties only, incoming ties only, both outgoing and incoming, and reciprocated ties only.
• Fixed bug in UNPACK procedure which was putting the wrong matrix label in the output datasets

• Fixed bug in new procedure Networks|Egonets|Egonet Strength which was incorrectly including reflexive ties in the calculations, and (for non-valued) data, was incorrectly averaging by dividing by the total number of nodes rather than degree
• Fixed bug in matrix algebra DIAGONAL function

• Added new procedure Networks|Egonets|Egonet Strength. It calculates the average attribute value of each ego's alters. For example, you can calculate the average centrality of each person's neighbors.

• Added simple Frequencies procedure to Tools menu
• Fixed bugs in Core/Periphery|Continuous program so that (a) it now allows users to change name of output partition file, and (b) includes node labels in the partition file

• Fixed bug in "count combinations" procedure which was causing output file to overwrite input file.

• Changed Data|Egonet procedure so that it would regard missing values as non-ties
• Changed networks|egonets|structural holes procedure:
  • Now outputs node degree and ego-betweenness
  • Default option is now ego model rather than whole network model, which affects the constraint procedure
  • added option for determining what value is given for constraint measure when degree is zero

• Added INTERSECTION procedure to Transform menu. A complement to the UNION procedure, it takes multiple networks as input, finds the nodes that are present in all of them, and outputs networks with just those nodes
• Added TIME STACK procedure to Transform menu. This procedure takes a collection of separate datasets with nodes in common (such as a network sampled at multiple points in time in which nodes appear and disappear), builds a single multidimensional matrix with all nodes that have ever appeared.
• Added some capabilities to the spreadsheet editor to facilitate selecting, inserting and deleted rows and columns
• In the spreadsheet editor, removed the ability to highlight a column by simply clicking on its first row

• Added "DIST" command to matrix algebra procedure. Allows you to compute geodesic distances on unvalued graphs & digraphs. If the dataset you give it has multiple relations, it will compute distance matrix for each relation. Example:
  -->distmat = dist(sampson)
  This would run geodesic distances on each relation in the Sampson dataset, and place the results in a dataset called "distmat".
• Fixed bug in Double-Dekker regression which caused crashes on some computers

• New installation program for UCINET. With this version of UCINET, the directory locations for UCINET and other Analytic Technologies programs have changed. The new locations are a bit more rational. However, there is a down side, which is that if you want this new version to replace your old one, you must uninstall the old one first. If you don’t uninstall the old one, you will end up with two versions of UCINET, and any shortcuts you may have created will call up the old version rather than the new. So, we recommend uninstalling the old version before installing this one.
• Fixed bug in Data|Subgraphs from Partitions. The automatically generated default output filename prefix was wrong -- it included a file extension and shouldn't have.

• Fixed recently introduced bug in Random Graphs|Erdos Renyi that was placing all ties in upper left quadrant of network.
• Modified installation program. More modifications to come. This may result in the program not being able to find NetDraw. If this happens, go to Options|Helper Applications and select Netdraw entry. Use browse button to find the netdraw program. It is probably located here:  c:\program files\analytic technologies\netdraw. ONce you find the folder, just click on netdraw.exe and from then on UCINET should be able to find it again.

• Fixed bug in Qap Regression interface that was preventing choosing multiple independent variables, one after another.
• Added additional output to Transform|Union to save vector indicating which original network a node was drawn from

• Changed options in hierarchical clustering to include two kinds of average link clustering -- one that is weighted by cluster size and one that is not.
• Fixed bug in the weighted average clustering. It had been weighting by the new size of the cluster (after merging) when it should have weighted by the old size.
• Fixed bug in spreadsheet that caused occasional "read past end of file" messages
• Fixed bug in Data|Attribute that created a default output dataset name that was not sensible.
• Fixed bug in Transform|Recode that caused intermittent failures to create output file

• Changed spreadsheet so that clicking on top left cell would not highlight entire column

• Changed Transform|Block and Networks|Cohesion|Density to accept "Identity" as a response to a prompt asking for row or column partition. This makes it convenient to calculate things like the number of ties that each node has to women and (separately) to men.

• Fixed bug in Data|egonet procedure, which was failing to save the ego net on disk (instead, it was saving the whole network).

• Fixed bug in help system that was preventing program from finding its help file
• Added frequency counts to the output of the Networks|Cohesion|Distance procedure

• Fixed bug in handling of filenames with spaces in them. Was causing two sets of full quotes to put around filenames.

• Fixed bug in Data|Join procedure creating output datasets with thousands of matrices.

• Fixed bug in Networks|Regions|Components|Valued which caused incorrect dendrogram when a solution resulted in the identity partition (where each node is in a class by itself). However, the saved HIPART matrix was always correct.

• Fixed calculation of the average permutation table in Relational Contingency table procedure
• Fixed full quoting of pathnames in several procedures including Data|Attribute
• Added option in Simmelian ties routine to allow outgoing ties only or require reciprocal ties
• Added output options to the QAP correlation routine

• Minor changes to export routine

• A few changes to dialogs in order to encapsulate filenames in full quotes.

• Added new facility for cross-tabbing matrices (e.g., social relations) against each other. Includes qap-based chi-square and correlation coefficients. Find it under Tools|Testing Hypotheses|Dyadic|QAP Relational Crosstabs

• Added new QAP Correlation routine to the main menu. Missing values are handled differently with respect to significance (p-values) and standard errors. In the old qap routine, the significance was based on Hubert's Gamma, which gives identical significances as correlation in the case of no missing values, but gives different values when missing values are present. Another advantage of the new routine is that it accepts more than two input matrices (and computes correlations among all possible pairs).

• Added QAP routine to Matrix Algebra facility. Syntax is as follows:
  
  --> qap "dataset1"  "dataset2"  "dataset3" ...
  
  Notice that if you include more than two datasets in the list, it will run qap correlation between all pairs of matrices. Also, if the dataset names contain spaces, you should enclose them in full quotes. Otherwise, the full quotes are not necessary

• Cosmetic changes to Dichotomize and Symmetrize procedures
• Changed Networks|Cohesion|GTD procedure to automatically disregard self-loops (diagonal of adjacency matrix)

• Fixed Permute function. When permuting order of matrices in a dataset, it was ignoring permutations of the rows and columns.

• Fixed bug in edge betweenness program which caused it to round all figures to nearest integer on saving. Printed values were unaffected as was the hierarchical decomposition

• Changed export to Pajek to include error message when attempting to export 2-mode data
• Changed name of default output file for bipartite procedure

• Added routine to matrix algebra to intersect graphs. Syntax is: <outdataset> = INTERSECT(<indataset1> <indataset2> ....). For example:  Y = INTERSECT(TIME1 TIME2 TIME3). The input is a set of networks. The output is a single dataset with multiple relations. The nodes are just those nodes that are found in all of the input datasets.

• Changed installation package. Thanks to Rich DeJordy, I think we have finally ironed out issues with upgrading to a new version so that you do NOT need to uninstall the old version (what a pain!).

• Changed method of scaling factor analysis scores to match SPSS. Also corrected a minor bug in their calculation.
• Enabled factor analysis routine to handle missing values

• Changed default output names for most procedures in the Data and Transform menus

• Fixed problem in cohesion|reciprocity routine that caused crashes when using a partition.

• Changed structural holes routine so that it would output dyadic statistics for large datasets as well as small ones
• Fixed bug in data|attribute causing it to prepend "from" to the default output file name, which screwed it up sometimes

• Some cosmetic changes

• Fixed bug in export to Pajek that caused crashes when not all fields where filled in.

• Added consensus analysis to Tools menu
• Fixed interface to double-dekker qap regression so it would have less trouble with pathnames containing spaces

• Altered Dichotomize to output a little more information

• Fixed bug in factor analysis program which was putting case labels where variable labels should have been when inputting 2-mode data
• Added feature to VNA import so that user could identify missing values

• Installation package now allows upgrades as well as new installations.

• Fixed Non-metric MDS routine when using Metric starting configuration. Thanks to Rich DeJordy for pointing this out.

• QAP regression updated to reflect the latest method by Dekker, Krackhardt and Snijders. It is called "double-Dekker semi-partialling".

• Changed Data|Attribute dialogue box so that it no longer prefixes "from-" in the output file name

• Fixed bug in E-I index procedure. In printing output from permutations, the values for internal and external ties were swapped. This was only a printing problem and did not affect the calculation of significance. Thanks to "analysisrussell" for pointing this out.
• This installation package includes NetDraw 2.9

• Some routines modified so that browsing for files automatically puts full quotes around the file name in dialogue windows. Without the full quotes, routines that expect input in the form of filename-space-dimension-space-integer get confused if the filename contains spaces. So if you put quotes around the filename, the program knows it is all one object. IMPORTANT NOTE: if you type the filename in yourself, the program will not automatically supply quotes.

• New installer implemented. Before downloading this version, you should uninstall the old version by using the Windows uninstaller (go to start|control panel|add/remove programs). Datafiles will not be removed by the uninstall.
• The new version handles multiple users of the same machine better, through making better choices of where to put things in the Windows registry. However, installation does require having administrator rights.

• Ok, this time I actually did change the default value of DisplayFullPathNames to True.
• Added support for three new DL formats for 3-dimensional datasets:
  • EDGELIST3. This is like edgelist2 except there are three columns that identify nodes: the row ids, the col ids, and to relation ids, as in
    labels embedded
    matrix labels embedded
    data:
    george event1 year2005 22.5
    george event1 year2006 0.0
    billy event3 year2006 1.0
  • EDGEARRAY2. This is like edgearray1 except for 2-mode data, as in:
    matrix labels:
    year2005, year2006
    data:
    george event1 22.5 0.0
    billy event3 na 1.0
  • LAURA. This format was built for Laura Savoia. It's like this:
    data:
                year05 year06
    george  team1  team1
    billy      none    team3
• In Jan 2005 degree centralization calculation was modified to yield values between 0 and 1 for valued data. Now (thanks to prodding by Giancarlo Oriani), I've extended the same change to the normalized degree centrality values. So all of these are just their old values divided by the largest edge value in the network.
• Fixed bug in structural holes dialog window in which it would only calculate full network constraint if the user specifically chose full network option. Otherwise it was calculating ego network constraint even if the dialogue window showed "full network". However, all outputs were always correctly labeled.

• Changed default value of DISPLAYFULLPATHNAMES option to true. This allows ucinet to easily navigate to different folders without getting confused.
• Added normalization option to affiliations procedure to allow dividing number of co-memberships by smaller of the two events. Also added ability to run multiple matrices at one time

• Fixed bug in Data|Remove Pendants which caused a crash when removing pendants removed all nodes in the network. Also hooked up the browse buttons.
• Reorganized Networks menu. Still changing.
• Modified Relational Contingency Table analysis procedure to allow non-symmetric data

• Fixed bug in Degree Centrality (asymmetric model) which was scrambling the labels when writing out to file.
• Fixed bug in hierarchical clustering (introduced yesterday) which caused crashes.

• Minor bug fixes in displays of tools|cluster|moca and tools|cluster|hierarchical clustering

• PERMUTE. Changed permute so that if you set the row permutation to RANDOM and set the column permutation to SAME AS ROWS, you permute both the rows and columns in the same random order (previously the rows and columns were randomized independently)
• UNION. Added option to allow adding up ties that are in common across two networks that share some nodes. So if network A has a tie between Billy and Johnny, and network B also shows a tie between Billy and Johnny, the new network will have a 2 for the relationship between Billy and Johnny.

• Changed structural holes procedure to (a) handle larger datasets, and (b) include an alternative method of calculating structural holes

• Changed how the degree centrality program calculates centralization on valued data. Now, the centralization value is divided by the maximum value in the input dataset, this ensures that it runs between 0 and 100%

• Fixed bug in spreadsheet -- previously, if you clicked on main window while in the spreadsheet, it reset the spreadsheet (clearing all cells).
• Added row and column indicator to spreadsheet. It can also be used to go to a particular cell.
• Fixed bug in data|export|excel that caused problems exporting datasets with multiple relations to excel on some systems.
• Changed dichotomize function to output real-valued matrices (to accommodate missing values).

• Fixed bug in ucinet system file reader -- it affected newer procedures that were trying to read interger-type files created by equally new procedures (such as Erdos-Renyi graphs).

• Nothing worth reporting

• Cleaned up output of Transitivity program
• Changed clustering coefficient program to operate on multiple relations in a file
• Changed Import|Raw procedure to more accurately guess the dimensions of the input data
• Fixed bug in Random|Erdos-Renyi procedure. When user selected multiple graphs, the program was constructing them cumulatively so that the density increased with each graph. Now they are separate and the density is identical for all graphs created.
• Fixed bug in Krackhardt GTD routine. Previously, it was failing to output measures to a disk file.

• Added measures of clustering adequacy to Tools|Cluster|Cluster Adequacy. Used to judge whether a partition does a good job.
• Fixed bug in Hierarchical Clustering program which caused E-I index to be calculated on a modified version of the proximity matrix (instead of the proximity matrix itself)

• Fixed bug in Reach Centrality procedure which caused incorrect values for the normalization of in-reach
• Added ability to select number of decimals when exporting vectors to Pajek

• Fixed bug in Data|Import|Multiple Dl files that caused problems with filenames containing spaces and other punctuation

• More finished version of 6.68

• Added two experimental routines that await serious testing: (a) Krackhardt's Graph Theoretic Dimensions (GTD) measures (Networks|Network Properties|Krack GTD), and (b) Reciprocity between groups procedure (Networks|Network Properties|Reciprocity)

• Added Erdos-Renyi random graph routine (Data|Random|Erdos-Renyi). It can create either directed or undirected graphs

• Replaced text editor with windows notepad

• Changed scatterplot facility so that user can drag points around in the map. The scatterplot procedure is used by the MDS programs and the Correspondence analysis program
• Modified Import|VNA procedure to be more forgiving of errors in the data.

• Major bug in RECODE function which caused random wacky numbers has been fixed
• Small but important bug in Tools|Similarities leading to slight inaccuracy in calculation of similarities between matrices has been fixed.
• Data|Export|Excel and Data|Import|Excel can now handle multiple relations/worksheets

• Added Export to Excel in main menu. Note that multiple relations/sheets are not yet supported
• Fixed bug in 'Subgraph from Partitions' which caused problems with 0/1 partitions.
• Added info to About box so you can tell whether a copy is registered or not.
• Browse button on Fragmentation now working

• Added ability to import VNA files (Data|Import|VNA). Only imports network and node attribute data -- node and tie properties are ignored.

• Added Fragmentation Potential metrics (drawn from KeyPlayer program) to Centrality menu

• Added "remove pendants" routine
• Added "spherical distance" routine under Tools|Dissimilarities in order to compute distances from latitude and longitude data, such as obtained from GIS/GPS systems
• Fixed bug in REGE which was converting all data with decimal places into integers
• Fixed bug in hierarchical clustering which was preventing it from saving cluster id variable. Also renamed the cluster id dataset from "tabuclus" to "clusterid"
• Changed starting cutoff value in dialogue box for "subgraphs from partitions" routine to 1 (was 3).
• Fixed bug in Extract routine which prevented usage of datasets stored (by ucinet) in a new internal format

• Modified UNION procedure to allow option of putting missing values (instead of zeros) for the links between graphs. Also modified the way it handles node labels when "match by labels" is not selected.

• Fixed bug in the Data|Import|Multiple DL files procedure that didn't allow selection of several files at one time in the file browse facility

• Completed addition of default output folder -- now all routines except one's that don't make sense for it should send outputs to the designated output folder.

• Added default output folder -- if non-blank, most routines will now direct output to that folder.
• Fixed bug in Recode dialog box causing an error message

• Fixed bug in reading Pajek net files that came in with version 6.37
• Fixed bug in exporting dl files in nodelist2 format (was writing "nodelist1" instead of "nodelist2")

• Fixed bug in EdgeArray1 data reader (thanks to Kate Lawrence for pointing it out). The problem was that for data with labels embedded and alpha=yes (the default) the program sorting rows and columns of the data matrix in alphabetical order, but not actually changing the labels, so the wrong labels were attached to each node.

• Changed hierarchical clustering to allow printing sideways textual dendrogram

• Fixed bug in hierarchical cluster analysis -- since version 6.43 it was saving the partition file (PART) incorrectly, resulting in bad graphical dendrograms

• Fixed major bug introduced in version 6.44 (April 9th, 2004). The import procedure was incorrectly reading dl files using fullmatrix format in which row labels were not embedded.

• Added facility for creating new networks (or matrices in general) based on boolean combinations of old ones. E.g., create matrix Y so that Yij = 2 if Xij > 0 and Zij = 34, and Yij = 1 otherwise. It is under Transform|Matrix operations|between datasets|boolean combinations.

• Enabled column/row delete functions in matrix spreadsheet

• Fixed bug in IMPORT DL procedures causing first letter of row/column labels to be cut off when reading files using Fullmatrix format.

• Hierarchical clustering now runs on each matrix in a 3-way dataset. Also includes some additional diagnostic output.

• Metric MDS changed to accept datasets with multiple matrices -- it automaticaly does a scaling on each matrix in the dataset.
• Correspondence analysis similarly changed.

• Fixed Remove Isolates to work with non-symmetric data and multiple relations
• Changed Tools|Dissimilarities procedure to enable multiple relations and to permit computation of distances between relations. Also added Hamming distance measure.

• Union procedure added to the Transform menu. Use UNION to combine separate graphs into one larger graph -- taking the union of all nodes and lines.

• Fixed bug in Permute procedure
• Added Remove Isolates procedure to Data menu. Provides one-step way to generate network with isolates removed.
• Added Extract Main Component procedure to Data menu. Enables user to create a subgraph representing the main (weak) component of a network

• Added new output to Brokerage routine that shows, for each actor, who they are brokering between.

• Added ability to import Pajek 2-mode net files
• Added ability select multiple files in the Transformation|Arithmetic|between datasets procedure, as well as the Data|Import|multiple dl files procedure

• Added additional QAP regression methods, including Dekker, Krackhardt and Snijders k-step semi-partialling method which is very slow but very accurate. For my money, though the fast ordinary semi-partialling is best choice because it is way faster and its only fault is being too conservative (doesn't reach significance often enough). But I'm sure Dekker, Krackhardt and Snijders would consider this a very irresponsible thing to say.
• Overhauled dl import routines to handle embedded labels better (especially ones containing spaces)
• Added multiple dl import routine to handle reading many files at once.
• Added arithmetic transformation routines to Transform menu; now, things that in the past had to be done via matrix algebra, can be done via menu interface
• Overhauled matrix algebra routine
• Non-metric mds routine has been changed to run on all layers of a multi-matrix dataset. Also, the bug that prevented running on matrices greater than 255 rows or columns has been fixed.
• Replaced the spreadsheet with a new one that is not limited to 255 columns. It can also do some limited transformations of the data.
• Changed the output.log browser so that seeing large output takes less time. For example, running Data|Display on large datasets used to take forever. It is a bit faster now.
• Added a spreadsheet-like matrix browser that is faster than the new spreadsheet for viewing large datasets in matrix form
• Changed input format for Recode procedure to facilitate more complicated recoding procedures.
• Adopted new installation procedure that is a little faster, a little simpler. Keyplayer is no longer included with UCINET installation.

• Changed output of geodesic distance procedure to suppress screen output for large datasets. Now processes a 5000 node dataset in 2 minutes. 

• Fixed bug in UCINET versions 6.04 discovered by Melissa A. Schilling in which degree centrality saves a centrality dataset that has the wrong labels. The numbers are right, and are in the original order, but the labels for the nodes are in the wrong order.
• Fixed bug in line (edge) betweenness program, which was causing problems reading the output file

• Added BETA TEST version of new partialling approach to QAP regression. Seems to work fast and well.
• Updated the version of KeyPlayer that is automatically installed with UCINET. Apparently, old version was missing a file.

• Changed default on line betweenness routine to not do Newman-Girvan hierarchical clustering automatically. See also changes in NetDraw.

• Modified edge betweenness procedure (Networks|Centrality|Betweenness|Lines) to automatically output hierarchical clustering of nodes obtained by successively deleting most central link and then recalculating

• F-Group procedure from UCINET 4 reinstated. No documentation as yet.

• Changed maximum flow & lambda set procedures to accommodate networks with more than 255 nodes. Now there is no limit.

• Added Options|Helper Applications, which lets you tell ucinet where netdraw, pajek and mage are
• default name for netdraw program is now netdraw1.exe

• nodelist and edgelist readers changed to allow names enclosed in quotes as in "John Smith" or "Smith, John Jr."

• Improved help file added. 
• More recent version of Netdraw added that allows text attributes (e.g., gender can have values of "male" and "female" and "not clear").

• More speed improvement on reading nodelist and edgelist files.
• Group centrality|Degree|Test routine fixed (was giving crazy answers and hanging up).

• Fast routines for reading nodelist and edgelist data files reinstated.
• Button added to Data|Egonet routine that allows selection of the focal nodes by choosing node names from list.

• Reach centrality procedure changed to (a) eliminate eccentricity (it will be added back to the closeness procedure later), and add new distance-weighted reach measure

6.08

• Hamming distance reinstated in QAP correlation routine
• Clustering coefficient output clarified

• New help files added
• The Tools|Dissimilarities procedure was fixed. It had been ignoring one cell in all computations, resulting a dissimilarity score that was only approximate. Thanks to Jim Moody for pointing this out.
• Continuous Core/Periphery routine altered so that its recommendation on where to cutoff the core is now based on the correlation criterion
• Expected values from the continuous core/periphery routine have been fixed -- Previously, the rows and columns had been sorted according to coreness, but the row and column labels were not changed, resulting in incomprehensible numbers. Now, the matrix is presented unsorted.

• Centrality routines now sort output automatically in order of decreasing centrality

• Netdraw graph drawing routine added.
• All routines that used to output a partition-by-actor vector or matrix now output an actor-by-partition matrix. This way, what are normally considered variables are always columns.
• Help files updated to include new procedures. NOTE: Netdraw still has no documentation. It's coming. 

• Edge Betweenness program fixed to eliminate the "can't open scratch file" error. 

• Now able to launch both Mage and Pajek programs from within UCINET. 
• Now able to import Pajek Net files
• Experimental degree group centrality procedures added. One procedure allows you to find which individuals should be included in a proposed group such that they have ties to as many different individuals as possible. Another procedure accepts a priori grouping (such as a set of managers) and measures their degree group centrality along and provides a statistical test
• Improved method of separating core from periphery when using the continuous core/periphery model, along with improved concentration measure.
• Changed current directory display to a drop down menu so you can easily go back to previous folder

• Fixed bug in Attribute procedure which lost the labels of nodes.  
• Improved optimization algorithms for structural equivalence and regular equivalence
• Bi-component routine now outputs a vector indicating for each node whether it is a cutpoint or not
• Components routine now outputs a vector indicating whether a node is in the main component or not

• Fixed bug in E-I index procedure which caused crash on some computers
• Improved display of the "loglinear" autocorrelation procedure (which basically does crosstabs of ties)

• Includes new routine for exporting to the METIS program, which can cluster graphs with millions of nodes extremely quickly. 
• Also includes a much faster betweenness centrality routine (relative to the one in versions 5.64 and earlier), using Ulrik Brandes' algorithm.

• Includes slightly improved routine for point-connectivity (# of node-independent paths between pairs of points). It is still very slow, though.
• Fixes bug in DESCRIBE that prevented imported labels from being saved.

• Adds betweenness decomposition routine which iteratively removes nodes with zero betweenness, yielding a core group of nodes that are mutually interdependent.

• Edge betweenness routine, ala Anthonisse has been added. Even newer version of betweenness implemented, using Ulrik Brandes' (Ulrik.Brandes@uni-konstanz.de) algorithm. It works with both symmetric and non-symmetric data. 
• New closeness routine added that calculates average length of all paths between two nodes, not just shortest paths. To be used with small graphs (< 100 nodes)
• Bug fixed in MRQAP causing near infinite standardized coefficient when there were more than 32767 ordered pairs of nodes. 
• Import>RAW routine improved to guess the number of rows and columns better when the entire dataset is in one row.

• Even newer version of betweenness implemented, using Ulrik Brandes' (Ulrik.Brandes@uni-konstanz.de) algorithm. It works with both symmetric and non-symmetric data. 
• Closeness and geodesic distance routines have also been upgraded to run faster with sparse data (switched from dijkstra to bfs)
• Mage export routine can now export 2-mode, rectangular datasets (as long as the number of points in the coordinates dataset equals the number of rows plus the number of columns in the 2-mode matrix
• Scatter plot routines (include MDS and Correspondence analysis) now include menu option for increasing or decreasing size of label font
• Mage export routine now allows you to skip the adjacency matrix and just input coordinates. 

• New version of betweenness implemented that typically runs around 3 times faster for typical graphs of about 1000 nodes. Algorithm courtesy of Mark Newman (mark@santafe.edu). However, it only runs on symmetric data (undirected graphs).

• Bonacich Power routine modified to allow non-symmetric data. 
• Right eigenvector routine added to matrix algebra procedure. To use, type REIGEN <filename>. Note this routine uses the power method and will only converge on a subset of matrices. 
• Instability in the mrqap regression routine was eliminated. Again. 

• Ability to export files to Pajek and Mage was added

• Bug fixed in SORT: it wouldn't recognize lower case letters in the dimension prompt of the dialog box.
• Instability in the qap regression routine was eliminated.

• There was an error in the egonet>density routine in some versions of 5.4 (I think earlier versions are fine), producing random numbers instead of the calculated values.
• There was a bug in the REGE routine so that all data containing decimal places were truncated. Numbers less than one but greater than zero were converted to 1s, and numbers greater than 1 were rounded to nearest integer. This bug goes back many years.
• In addition, a new routine was added in the statistics menu, enabling users with krackhardt-style css data to test for significant differences in different aggregations of the data (for example, comparing the aggregate female matrix with the aggregate male matrix). No documentation is available yet.
• Several minor fixes, including the default output name of the dichotomize procedure.

• This version fixes a major design error in the density or anova-based categorical autocorrelation routine. In previous incarnations, the routine calculated r-square correctly, but the significance test was biased, yielding significance too often. The routine has been completely replaced and now calculates significance correctly. In addition, it gives additional informative output.

• Adds Gould and Fernandez brokerage measures.
