Re: [PyMOL] how can quickly make a fractional atoms into one

Well, for me at least it is a good think Lina asked, because there were two different answers from the experts and i learned from each. I don't think we want to discourage or intimidate new users from asking questions. It is very easy to ignore or delete a silly email. Marius Retegan wrote: > Dear

2011-11-26 Thread Edward A. Berry
While the single acceptor H-bond is most common, bifurcated (or three-centred) H-bods are not uncommon in crystal structures, as described starting page 22 of GA Jeffrey's book: http://www.amazon.com/Introduction-Hydrogen-Bonding-Physical-Chemistry/dp/0195095499/ref=sr_1_2?ie=UTF8&qid=1322331503

Have you tried opening a dos window and: ftype pdbfile=C:\wherever\pymol.exe %1 assoc .pdb=pdbfile If that doesn't work you can make the associations directly in the registry, but its more complicated. Jacob Keller wrote: > Dear List, > > I have v.1.41 running on windows 7 64 bit, an

Re: [PyMOL] electron density map

2012-11-01 Thread Edward A. Berry
The electron density we usually display with an atomic model is based on experimental diffraction data (usually x-ray). The purpose of the density map is usually to validate the model, i.e. show it is consistent with the map calculated using experimental data. Even for many structures that are at t

Re: [PyMOL] Obtaining accurate FASTA sequence from PDBs

2014-03-31 Thread Edward A. Berry
Due to the possibility of insertion codes and non-sequential residue numbering, I believe there is no way to avoid aligning the residues in the ATOM records with the sequence in SEQRES in order to find gaps. I don't know of a program to do this. The structure validation server at RCSB ADIT2 makes t

Re: [PyMOL] disulbond break

2014-05-14 Thread Edward A. Berry
That would seem to violate rule #1 of macromolecular depiction: Never change the coordinates! But then I can't imagine why one would want to not draw a disulfide bond in a real protein structure, so maybe this is some kind of exercise where it is not important to adhere to the experimental results,
