Is it not just a case of adding "beta sheet restraints" in the real-space refine options menu?
If it goes back to a loop during refinement then that may mean that the atomic positions don't meet the requirements?

Peptide should be in the form of Sheet, after multiple cycles of refinement peptide still in the loop form. If anyone could help me, how to convert this loop structure into a sheet in coot , would be very helpful? I am using ccp4-Refmac5 for the refinement. Thank you Rohit -- Regards Dr. Rohit Kumar Singh ________________________________ To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1 ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1 This message was issued to members of www.jiscmail.ac.uk/CCP4BB, a mailing list hosted by www.jiscmail.ac.uk, terms & conditions are available at https://www.jiscmail.ac.uk/policyandsecurity/
