Re: [ccp4bb] per-residue RMSD calculation for homologous structure

2010-11-22 Thread Eleanor Dodson

SSM - see superpose task under Coordinate utilities.

This matches secondary structure and gives RMSD for CAs - inceredibly 
useful program..

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? I looked on the web but all the software that I 
found require the sequence to be the same for both structure.

Thank you

This is not a well-defined calculation.
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.

 most modern programs perform some kind of local-global alignment first
to define the corresponding residues and then compute the statistics.

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.

 Good luck

Bashir
