I have some problems with chimera. I would like to ask you.When I open a gro file with chimera, it always shows that it is being opened, but it just won't open.Then, after I opened the PDB file, want to use the Find Clashes/Contacts function, click to Designate button but no response, asked a lot of the others didn't get a reply.This makes me very distressed. I am looking forward to your answer to my question. Thank you!My system is WIN7.
