Re: [ccp4bb] fix b-factors/coordinates during refinement

Dear Nick, I managed to get the result you wanted in 3 steps: 1) create a copy of the ped file you want to refine but removing the B Column (easily done in emacs for example) 2) run refmac with no B-refinement 3)paste the B-factors back in the refined file Far from being elegant, but takes real

What happens if you use REFI BREF Overall with a Boverall of 0.0? It might just keep the given atomic B factors and add 0.0 to them? Eleanor On Wed, 20 Feb 2019 at 12:06, Pearce, N.M. (Nick) wrote: > But no way to fix to a set of refined/parametrised Bfactors and refine? > (That’s the one I wan

But no way to fix to a set of refined/parametrised Bfactors and refine? (That’s the one I wanted most). I.e. “refi coordsonly”. Thanks, Nick On 20 Feb 2019, at 12:47, Jon Agirre mailto:jon.agi...@york.ac.uk>> wrote: Hi Nick, you can refine B-factors while leaving coordinates untouched by usin

Hi Nick, you can refine B-factors while leaving coordinates untouched by using the 'refi bonly' keywords. You can also preset an average (e.g. Wilson B) and have refmac do coordinate refinement ( http://www.ccp4.ac.uk/html/refmac5/keywords/xray-principal.html#refi). Cheers, Jon On Wed, 20 Feb 20
