[ccp4bb] modified amino acid

2015-05-29 Thread Bio Physics
Hi all, I have a modified amino acid (covalent complex), during refmac5 refinement it isolated from next residues. Phenix does well though with the same .cif file. I know people are doing this every day in refmac. Any help please?

Hi Emilia, Did you construct the map at the same sampling rate as COOT uses? This makes a big difference. You can also just use CCP4mg. You can make very nice pictures with that and you can do all the map things there. CCP4mg supports mtz files directly, so no mucking about with map files. I

Hello. I am struggling with an old question--old because I've found several discussions and wiki bits on this topic, e.g. on the PyMOL mailing list ( http://sourceforge.net/p/pymol/mailman/message/26496806/ and http://www.pymolwiki.org/index.php/Display_CCP4_Maps), but the suggestions about how to

Hi Smith, You're possibly looking at a turn of 3_10 helix: http://en.wikipedia.org/wiki/310_helix Whether it's real or not will of course depend on your electron density. Shane Caldwell McGill University On Fri, May 29, 2015 at 11:35 AM, Smith Liu wrote: > Dear All, > > Even with the Coot se

Dear All, Even with the Coot secondary structure (for example helix) restraint selected and by this way we keep the secondary structure, I find the protein secondary structure formed in this way was not so typpical, for example, not all CO ( i) and NH (i+4) forms H-bonds, and there are H-bonds
