Dear Appu, you give very little details, so it is not possible to give very specific advice. Here are some general points: -the Mw of your protein is 36 kDa, what is the Mw of the ligand binding domain and of the DNA binding domain? If the ligand binding domain is a seizable part of the total,

Hi Ian, The warning refers to a MET 59 in chain A whereas you only have MET 72. That is very suspicious. Non-sequential residues further apart than x Angstrom automatically get a gap record. Have you tried a newer version of Refmac, because this feature was added quite a while ago? What is your

Hi Robbie OK I just realised what's going on. In my script I renumber the input PDB file (starting at 1 for each chain and incrementing by 1) and keep the mapping so I can renumber it back afterwards for human consumption. So you're completely correct: there is indeed a residue A59 after

[ccp4bb] [Rendering Problem] Pymol VMD conflicts Coot

Hi all, I am sorry that I ask something a little bit irrelevant here. I am a newbie in Linux, and recently installed Coot, Pymol and VMD on Ubuntu 12.04. It took me a while to figure out a strange conflict among them on my machine. If I remove the mesa-swx11 package, Coot becomes crazily slow.

Hi Ian, I avoid renumbering whenever I can. If I do have to renumber things (e.g. to get proper connectivity in PDB entry 2j8g), I do it by hand. So no help there. As for dealing with insertion codes in general, why not try to convince the developers of the 'brain-damaged' to support insertion
