Re: [ccp4bb] RMSD of dimers

Hi all, Just writing an update, as I have had two people contact me asking if I had found a solution and if I could share. I would like to apologize first for not phrasing my question to describe the situation simply. I had several suggestions that Coot, and PISA could do it but actually can no

No, the question seems to be slightly different. While one can use either CCP4's SSM or GESAMT to superpose 2 dimers, these algorithms would balance RMSD between both chains and produce something optimal for both chains. What is required, however, is optimal superposition on one pair of chains

Doesnt pisa give you some of this information? It lists all likely homodimers and I think gives RMSD too Eleanor On 24 February 2015 at 22:00, Thomas Holder wrote: > Hi Dan, > > gaps/insertions should be no problem for PyMOL's rms_cur command, as long > as chain identifiers match (and all other

Hi Dan, gaps/insertions should be no problem for PyMOL's rms_cur command, as long as chain identifiers match (and all other atomic identifiers!). See http://pymolwiki.org/index.php/Fit for a description of the matchmaker argument. Cheers, Thomas On 24 Feb 2015, at 16:30, D Bonsor wrote: >

I have a family of homodimers (denoted A1B1, A2B2, A3B3...) which I have superimposed using Chain A. Several programs will produce the RMSD of Chain A2, A3, A4... to Chain A1. However, I would like to know the RMSDs of Chain B2, B3, B4... to Chain B1 when I have superimposed the structures relat
