[ccp4bb] Problems with adding ncs matrixs in PHENIX

2010-12-02 Thread chen c
I am working on a data set of an T=4 icosahedron protein crystal, employing molecular replacement methods. I've consulted a professor, he told me that my crystal is in fact isomorphous to the model so that there is no need for MR. So I figured such command lines: phenix.refine output.mtz model.p

Hi, for each PDB file run: phenix.pdb_interpretation model_1.pdb ligand.cif phenix.pdb_interpretation model_2.pdb ligand.cif ... phenix.pdb_interpretation model_N.pdb ligand.cif and it will result in a buch of output files model_1.pdb.geo model_2.pdb.geo ... model_N.pdb.geo where each *.geo fil

Dear All, I have set of pdb files (few hundred), which contain the same ligand. I would like to get values for chosen torsion angles of ligand. I know I can do it manually (what would be painful and time consuming) but maybe someone does know smarter and more automated way of doing it? I would

If you will replace link line with the following LINKRC1 NAG A1003 ND2 ASN A 611NAG-ASN Then it should be read by refmac and by coot. And restraints should be applied properly regards Garib On 2 Dec 2010, at 06:49, Dr. STEPHEN SIN-YIN, CHUI wrote: >

I dont think that isnt the correct format for a LINKR record. LINKRC LEU A -1 N CYG A 0LEU-CYG LINKRC2 CYG A 0 N SER A 2 CYG-SER It is like this - it points to a named LINK entry in your restraints library eg LEU-CYGun refm

Easiest to follow the documentation.. http://www.ccp4.ac.uk/dist/html/dm_ncs_averaging.html You get the matrices most easily by mapping A to B A to C etc using lsqkab if you want to average over the A molecule.. Eleanor On 12/01/2010 05:41 PM, Francis E Reyes wrote: Hi all I'm trying to f
