Dear VMD users and developers:

I have 200 pdb structures taken each 50ps from an MD trajectory. I want to
eliminate the redundancy and find the non-overlaping set of structures that
represents the dynamics of my system. The problem is that when I try to
search for the non-redundant set using the srtucture QR(after aligning my
structures with STAMP) (with what ever QH cut-off) I dont get nothing,
actually it looks as if nothing happens at all. If I use the sequence QR
instead I get results but I will get one representative only.

Im I doing something wrong? Should I get a selection after the process? It
is enough to use the Qres tree from the pylogeneric tree menu??

Any help will be appreciated.

PS: I've done this same proces with VMD 1.87 in lunux and mac...
