Would a simple hack, like renaming all of the atoms in each file to be 'CA' and then using a conventional alignment program work? Maybe I am caffeine deficient at the moment, but that seems worth trying.

I think what she is asking for is a program that detects which atoms should be matched to which, irrespective of their names (i.e., not assuming they are called " CA ") and order (i.e., not nicely sequential such as amino-acid residues), and then applies the operator that follows from that. --dvd On Fri, 26 Feb 2010, Kevin Cowtan wrote: > SSM is also available in Coot and CCP4MG of course... > > > Eleanor Dodson wrote: >> would ssm serve your purpose? >> >> eleanor >> >> ebi or ccp4i >> >> >> >> Miri Hirshberg wrote: >>> Sun., Jan. 17th 2010 >>> EBI >>> >>> Greetings, >>> >>> I am looking for a 3D structure superposition program which takes >>> two structures and superpose them based only on the coordinates X,Y,Z >>> regardless of of residue/atoms name. >>> >>> (both files are in PDB format) >>> >>> Thanks >>> Miri >>> >>> ------------------------------------ >>> Dr Miri Hirshberg >>> European Bioinformatics Institute UK >>> PDBe - EBI -EMBL >>> http://www.ebi.ac.uk/pdbe >>> >>> Phone: +44 (0) 1223 492647 >>> FAX: +44 (0) 1223 494468 >>> ------------------------------------ > Best wishes, --Gerard ****************************************************************** Gerard J.
