Hi all, When I build a custom ligand using the coot Ligand Builder (0.7.1-pre (revision 4650) [with guile 1.8.8 embedded] [with python 2.7.3 embedded]).
Coot then runs cprodrg and generates restraints which I can use inside of coot to do all my refinements and even run refmac from within coot. When I however write out those restraints from coot using --Edit- Restraints - Pick DRG - save as mmcif and use the generated cif with refmac (CCP4 6.3: Refmac_5.7.0032) I get an error in the refmac log( see below) Is there some conversion I need to do to the coot saved mmcif file to be able to use it inside refmac. Thanks Hari ############ refmac log excerpt ############# " I am reading library.
