**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)

**COMMENTS** None.

**REFERENCES** None.
