Re: [ccp4bb] 3D fitting

2010-02-26 Thread Garib Murshudov

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)

A non-CCP4 (PHENIX) solution is:

phenix.superpose_pdbs fixed.pdb moving.pdb selection_fixed="chain A and name 
XY" selection_moving="chain B and name ZX"


which is not as automated as desired since you need to define (manually,

superposition.

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.

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.

Pavel.
