DATA > EXPORT>DL 

PURPOSE Convert UCINET data files into DL format.

DESCRIPTION Converts UCINET data files into DL format, for a full description of the DL format go to help dl . 

PARAMETERS
Input dataset:
Name of file containing data to be exported. Data type: Matrix.

Output format : (Default = "Full matrix")
Choices are:

Full matrix 
A complete N´N matrix;
   
Lowerhalf
Gives the lower-triangle and should only be used for symmetric matrices.

Upper half
Gives the upper-triangle and should only be used for symmetric matrices.

Nodelist1
This is used on binary matrices only. Each line of data consists of a row number (call it i) followed by a list of column numbers (call each one j) such that x(i,j) = 1. 
 
Nodelist1B 
This is used on binary matrices only. Each line of data corresponds to a matrix row (call it i). The first number on the line is the number of non-zero cells in that row. This is followed by a list of column numbers (call each one j) such that x(i,j) = 1. Note that rows must appear in numerical order, and none may be skipped (unlike the Nodelist1 format).

Nodelist2
Each line begins with a row id number followed by a list of column id numbers that are connected to that row number. For use in 2-mode matrices
    
Edgelist1 
This format is used on data forming a matrix in which the rows and columns refer to the same kinds of objects (e.g., an illness-by-illness proximity matrix, or a person-by-person network). The 1-mode matrix X is built from pairs of indices (a row and a column indicator). Pairs are typed one to a line, with indices separated by spaces or commas. The presence of a pair i,j indicates that there is a link from i to j, which is to say a non-zero value in x(i,j). Optionally, the pair may be followed by a value representing an attribute of the link, such as its strength or quality. If no value is present, it is assumed to be 1.0. If a pair is omitted altogether, it is assigned a value of 0.0. 

Edgelist2 
This is used on data forming a matrix in which the rows and columns refer to different kinds of objects (e.g., illnesses and treatments). The 2-mode matrix X is built from pairs of indices (a row and a column indicator). Pairs are one to a line, with indices separated by spaces. The presence of a pair i,j indicates that there is a link from row i to column j, which is to say a non-zero value in x(i,j). If the pair is followed by a value then this is the strength of the tie. If no value is present, it is assumed to be 1.0. If a pair is omitted altogether, it is assigned a value of 0.0. 

Diagonals present (Default = Present)
If Absent diagonal values will not be written to file.
 

(edgelist only) Type
Specify whether the data is directed or undirected
 
Decimal places: (Default = 0)
The number of places of decimals required.  The default will correspond to the number of places of decimals in the original UCINET data file.  A smaller value will result in rounding to the nearest value.  A value of 0 will indicate Integer values only.

Field width (Default = Freefield)
Freefield will simply place each row of a matrix on a new line with no attempt to align the columns.
Automatic will align the rows and columns into a matrix format.  The user can also specify the number of spaces for each field - this number should be greater than the number of decimal places in the field.

Guaranteed space (Default = Yes)
Yes separates each number in every row by a space.  No prints each number in a continuous list.

Page width (Default=10000): 
The maximum width of the output page.

Embed row labels(Default=No):
Should these labels be embedded.

Embed column labels(Default=No):
Should these labels be embedded.

Embed matrix labels(Default=No):
Should these labels be embedded.

Output dataset:
Name of file to be created with .txt file extension.


LOG FILE A text DL data file of type specified.

TIMING O(N^2)
