Hi Francis, it is supposed to work for nucleic acids no problems... Can you send me the PDB files and I will have a look? Pavel On 12/14/11 10:52 AM, Francis E Reyes wrote:
Hi phenixer's.
I need to do a superposition of two pdbs. I guess phenix.superpose_pdbs is my jiffy but it doesn't seem to work for nucleic acids (tried selection = 'name P' or selection = 'all'). LSQKAB seems to have the same limitation. They are the exact same PDBs (1 to 1 atom/residue mapping) but just shifted and rotated relative to the other. I need a superposition or the transformation matrix for all atoms.

I may just strip it down to phosphate's and rename the residues to ALA but a quick phenix jiffy would be great.
Thanks!
