filtering nodes

[gvsbdisco]

I am analyzing a twitter network. I have filtered the edges based on "NOT" "Follower" which leaves me the more interesting edges that indicate replies, mentions etc. My question is after doing the edge filtering how do i get ride of the unconnected nodes in the graph? I thought after filtering I could re-run the statistics and it would take into consideration the removed edges thinking i could then filter out nodes based on degree, ie. get rid of the nodes with a degree of 0. That does not seem to work. Thanks for any direction.
