Hi Jürgen, it should properly take symmetry into account. I would be very surprised if it doesn't. Pavel On Sun, Nov 18, 2012 at 9:14 AM, Bosch, Juergen wrote: > Hi Pavel, > > does this also work for symmetry related atoms ? > > Jürgen > > .. > Jürgen Bosch > Johns Hopkins

Hi Rex, as easy as: phenix.pdb_atom_selection model.pdb "within(3, chain L and resseq 9 and name CA)" --write-pdb-file=cut.pdb which in the above example selects all atoms within 3 A from CA atom in chain A of residue number 9, and writes them into cut.pdb file. Pavel On Sat, Nov 17, 2012 at 1

Hi, You can do this with MOLMOL. The official page from Wuthrich's group seems to be no longer supported. You can find it on the web from several other websites. For example: (http://pjf.net/science/molmol.html), ( http://blog.louic.nl/?p=397). 1) SelectAtom '#1:10@CA' (Structure 1, residue 10,
