2. Set default folder to your datafiles folder (probably c:\program files\analytic technologies\ucinet 6\datafiles)
3. Go to Data|Unpack and unpack the Wiring dataset. This will create a series of datasets, one for each relation in the Wiring dataset. Here’s how to fill out the form:
The output is mostly new datasets that you will find on the hard disk. However, the output log will tell you the names of the files created:
UNPACK MULTI-RELATION DATASET --------------------------------------------------------------------------------

4. Display “rdgam” dataset created in the step above. Should look like this:
DISPLAY --------------------------------------------------------------------------------

6. Run Network|Cohesion|Distance. Use RDGAM as the input dataset as follows:
The output should be this:
DISTANCE --------------------------------------------------------------------------------
Type of data: ADJACENCY Nearness transform: NONE Input dataset: C:\Program Files\Ucinet 6\datafiles\rdgam
For each pair of nodes, the algorithm finds the # of edges in the shortest path between them. Average distance (among reachable pairs) = 2.091 Distance-based cohesion = 0.462 (range 0 to 1; larger values indicate greater cohesiveness) Distance-weighted Fragmentation = 0.538

Note that some distances could not be computed. This is because the network is disconnected – there are two isolates.
7. Verify the disconnectedness of the network by using NetDraw to draw a picture of RDGAM. (In Ucinet, press the Netdraw button. When Netdraw starts up, press open file button and select rdgam.) You should get this:
Note the two isolates at the top left.
8. Run Network|Regions|Components|Simple graphs. Use RDGAM as the input dataset. The result shows 3 components. In addition, the end of the output indicates that a dataset called InMainComp was created.
COMPONENTS --------------------------------------------------------------------------------
Input dataset: C:\Program Files\Ucinet 6\datafiles\rdgam
Kind of Components: WEAK
3 components found.

9. Display InMainComp to understand what it is. It looks like this:
1 M - 1 I1 1 2 I3 0 3 W1 1 4 W2 1 5 W3 1 6 W4 1 7 W5 1 8 W6 1 9 W7 1 10 W8 1 11 W9 1 12 S1 1 13 S2 0 14 S4 1
The file is a column vector of 1s and 0s. A 1 indicates that the node is a member of the main component and a 0 indicates that the node is not a member of the main component.
10. Use InMainComp to extract the main component of Games as follows. Go to Data|Extract. Fill out prompts as follows:
(Note: if the goal is to extract the main component from a network, there is an easier way. Simply go to Data|Extract Main Component.)
11. Use Network|Cohesion|Distance to obtain geodesic distances on MainGamesNet. Verify that all distances are now computable.
12. Run Network|Cohesion|Maximum Flow on MainGamesNet. Can also run on RdGam for comparison.
13. Run Network|Cohesion|Point Connectivity on MainGamesNet (can also run on RdGam for comparison).
14. Run Network|Regions|BiComponent on MainGamesNet.
15. Run Network|Network Properties|Density on MainGamesNet and RDGAM. |
