Re: [ccp4bb] per-residue RMSD calculation for homologous structure
SSM - see superpose task under Coordinate utilities. This matches secondary structure and gives RMSD for CAs - inceredibly useful program..

[ccp4bb] per-residue RMSD calculation for homologous structure
Hi All does anyone know any software that can calculate and print out RMSD of every residue (c alpha will be good) for homologous structures which has only 30-40 % sequence similarity?

In regions where the structures do not superimpose well, how do you decide which C-alpha pairs with which? What about insertions/deletions? Usually it only makes sense to calculate RMSD over those residues which line up structurally, so it won't be every residue.

Re: [ccp4bb] per-residue RMSD calculation for homologous structure
I looked on the web but all the software that I found require the sequence to be the same for both structure. most modern programs perform some kind of local-global alignment first to define the corresponding residues and then compute the statistics. BR
Re: [ccp4bb] per-residue RMSD calculation for homologous structure
Dear Dhiraj; Please try the following web site http://www.cgl.ucsf.edu/home/meng/grpmt/structalign.html Here you will find a number of option for structure base sequence alignment no matter what is the similarity of your structures. Regarding the RMSD of every residues you can find this option by using the Dalilite server.
