Now select the same file again (lis4508cdew.min) Now, run Analyze/Co-occurrence/Join clusters

The pe5-file was created and contains all links used for making clusters and also links that join clusters Select pe5-file and run Mapping/Make net file for Pajek… Then select the pe2-file and run Mapping/Create clu-file

Open the net-file and the clu-file in Pajek and then use Net/Vector/Summing up values of lines/All to get node sizes. Then Draw/Draw-Partition-Vector

Here clusters are joined by only one link
