Hi All, I've just found the RRdistance Map function on Chimera and would like to compare between structures. I would like to: 1- make contact map of protein 1 to protein 1 with a cutoff of about 6 angstroms 2- make a contact map of protein 2 to protein 2 with a cutoff of about 6 angstroms 3- compare these two contact maps using the colors available for the whole contact map. I can only seem to compare the ENTIRE contact map of protein 1 to the ENTIRE map of protein 2, whereas I'd like to mask any contacts over 6 angstroms. Alternatively, if anyone knows of a way to export residue lists of contacts from the contact map site I could just compare them that way. ALSO: Anyone know of a way to map defined attributes onto a contact map? Thanks so much! Sincerely, Nicky
