Re: [ccp4bb] 3D fitting
One option would be molrep molrep -m -mx Of course it assumes that your two structures have overall similar structures and no substantial conformational changes. As the question posed, I think, it does not have solution (only approximations). Almost all programs assume either atom labeling or shape similarity (molrep assumes shape similarity). If you have connectivity and the number of atoms is small then graph matching would work fine (at least it would give correspondence between atoms and then it is just matter of calculating rotation matrix and applying it) Garib On 26 Feb 2010, at 15:11, Kevin Cowtan wrote: SSM is also available in Coot and CCP4MG of course...

Re: [ccp4bb] 3D fitting
No, there would still be an order involved. I think she wants to superimpose two small molecules with arbitrary atom names. So she needs a subgraph isomorphism detector without constraints on the labels and ordering of the vertices (atoms), but which is not scale-free (as we want low RMSDs as opposed to mere topological equivalence). But I'm just guessing. --Gerard On Fri, 26 Feb 2010, Soisson, Stephen M wrote: Would a simple hack, like renaming all of the atoms in each file to be 'CA' and then using a conventional alignment program work?

In ccp4i select "Coordinate utilities/Superpose" And then on the first menu select "Superpose using secondary structure matching". It will automatically superpose based on fold rather than atom alignment. (This is the same software as used at the EBI for what used to be called MSDfold).

Hi Miri, you can do this (and more) using a tool from PHENIX: phenix.superpose_pdbs [pdb_file_fixed] [pdb_file_moving] [parameter_file] A couple of examples: phenix.superpose_pdbs fixed.pdb moving.pdb selection_fixed="chain A and name CA" selection_moving="chain B and name CA" phenix.superpose_pdbs fixed.pdb moving.pdb More details you can find here: http://www.phenix-online.org/documentation/superpose_pdbs.htm Please let me know if you have any questions or problems using this tool.
