Hi, You can save the rigid fit model w.r.t the density map in chimera, then load them in phenix to start real space refinement. Regards Subhomoi On Thu, 19 Dec, 2024, 6:24 pm tim smith, wrote: > Thank you all for your responses. I was confused after open file in coot > and did some regid refi

Thank you all for your responses. I was confused after open file in coot and did some regid refinements. That file was saved, after this what I understood I can use this file for phenix real space refinements right or without doing in coot can do directly?. Can any suggest me my fit doesn't look li

I guess you mean that you’ve done an initial global rigid body fit and you still want to do some refinement to get better local fits? Refmac servalcat is a good option and uses two half maps in MRC format. It comes as part of ccpem but does require ccp4 to be installed too Or alternatively, you

Hi all, Can you please advise once we fit the map and open in coot. What is next step to do in coot. I tried refmac but that required ccp4 file which doesn't have. Please some one can help in elaborating and sharing any tutorial would be helpful. I'm new bie and first time I am trying model buildi
