Re: [PyMOL] finding complete residues within a RANGE OF distance cutoff

2012-02-29 Thread Thomas Holder
Hi Anasuya,

your question is related to this one from September last year:
http://www.mail-archive.com/pymol-users@lists.sourceforge.net/msg09588.html

In short (example with heme as ligand):

select ligand, chain A and resn HEM
select shortrange, byres (polymer within 4.5 of ligand)
select midrange, byres ((polymer within 9 of ligand) and not shortrange)

Relevant reading:

Cheers,
   Thomas

 Hello ,

 I want to extract out complete amino acid residues which fall within a radius
 of 4 to 9 Angstroms from the ligand.

 What do I do in such a case, given the pdb id's, chain ID,  the name of the
 ligand and its residue id?

 PS: I want to avoid, extracting out cmplete residues within a 0-4.5A first AND
 THEN getting residues from 4.5-9A.

 Is there a direct way to do this?

 Please let me know.
