[ccp4bb] edit chi angles of DNA in coot

2013-01-27 Thread LISA
Hi all, I am refining a protein-DNA complex. But when I adjust the position of DNA by "edit chi angels", the phosphate does not move. Only the sugar and base move Here is partial DNA pdb. Is there any format problem of my pdb or I miss some library? ATOM 10825 PAd D 11 17.140 11.607 4

Hi Lisa, I'm not sure it's the source of your problem, but your atom names are still in PDBv2 format. That's 'so last decade'. Start by fixing that. There must be a CCP4 tool that will do that. You can also use the MolProbity server to fix the format. For the developers: the problem with atom a

Yes, a good pdb converter jiffy that picks up and corrects/highlights differences and errors in the atom name from the residue name would be great to have. I’m using pdbvconv from Global Phasing which is pretty good. It gets a little confused when the atoms names are a mixture of pdbv2 and v3.

There is a new tool for that in CCP4, pdb2to3. It will try to convert everything what is convertible, even when it is not "PDB2" or residue names do not match, by applying graph matching and some heuristics. Eugene On 27 Jan 2013, at 13:27, Robbie Joosten wrote: Hi Lisa, I'm not sure it's the

I use the Zalman 21" monitor and it works great. Glasses from 3D movies work, so when students go to the movies I ask them to save a pair of glasses for me. It's easy and cheap - software controlled so works on all crystallographic packages that I've tried thus far. Frankly, since going to an

Hello Sabine, the Asus VG287H (not the HE model)! Why? - nvidia certified, so all nvidia drivers will recognize the screen correctly (we have it working under SuSe linux and windows 7) - build-in IR emitter (so works with the cheaper quadro cards), we run it with quadro 600, k1000m and 2000 mo
