Hello, Have you tried ISOLDE? Interactive MDFF is really powerful both for fixing models with poor geometry and for improving fit to the map. There is a good tutorial for refinement of a model against a cryoEM map with ISOLDE:

Would the stepped refinement protocol in Coot do what you want? It does a real space refinement for every residue automatically. Cheers Christian On Wed, Jul 29, 2020 at 5:20 PM Schreuder, Herman /DE < herman.schreu...@sanofi.com> wrote: > Dear BB, > > > > I would like to do a real

Hi Herman, There is lots of information on CCP-EM's modelling tools here: https://www.ccpem.ac.uk/training/icknield_2019/icknield_2019.php This includes a tutorial on Refmac. As you note this is done in reciprocal space but the CCP-EM pipeline handles conversions from MRC to MTZ format

Coot does it, but if one wants to do it for a complete protein, it is a lot of clicking. On the other hand, I have not tried to just select the N- and C-terminus for real-space refinement to see what happens. I would prefer to have some script to do it. Best, Herman Von: Eleanor Dodson

Dear BB, I would like to do a real real-space-refinement of a protein against a cryo-EM map; not the mtz-based Refmac approach. A quick internet search produced a lot of Phenix hits, but little ccp4 hits. Does somebody know how to do this using ccp4 programs, or has someone a Coot script to do

Hello, have you tried anisotropic B-factor refinement? It is usually very good at cleaning-up the difference map. At that sort of resolution, you may still have some way to go in the refinement since the R and R-free usually go to about half of what you have, at least with proteins. Best
