Dear Jon, in SHELX(L), you can name your atoms foo and bar, or jon and doe, if you like. The scattering factor is derived from the number next to the name. The name is just that, and identifier. Best, Tim On Monday, February 3, 2020 9:20:03 PM CET 0c2488af9525-dmarc- requ...@jiscmail.ac.uk

[ccp4bb] Refmac5 question

2020-02-04 Thread Joern Krausze
Dear all, I've got a Refmac5 question. When I refine my protein structure in Refmac5 with the options make hydrogen ALL and make hout yes, some of the hydrogen atoms in the output file have zero occupancies. At a first glance, only the the H-atoms attached to OG1 of Ser, ND2 of Asn, and NE2 o

Hi Joern, The logic behind it this is that those are hydrogen position that are uncertain due to possible flips and free rotation (tyr, thr, ser). You should probably only set these occupancies to 1.00 after you have studies the local hydrogen bonding network. Cheers, Robbie > -Original

Thanks, sorry, shelx is wonderful! I was thinking back to shelxpro days when your hetero-atoms could acquire the wrong scattering factors if they were not positioned right in the pdb file. The classic, which I saw several times, was calcium (CA) being treated as an alpha-carbon (CA), and I think re
