Next, we need choose to use modularity class to  do filtering under the tab of “Filter”

After we clicked Filter button, you can see that there are only 1788 of 4555 nodes left. We can save and work on this filtered data.

By clicking Workspace 2 tab, you now work in Workspace 2 ( the exported filtered data).   You can then export the date in this workspace to a graphml file.
