hi, i have to use mmCif format for my structure. pymol, phenix and molprobity seem ok with it. as i try to fix issues with coot i run into problems every residue seems to have the same number -2147483647 which confuses me and also i think confuses coot. this is coot version 0.8.9 any suggestions ? forgive me if there is a coot place to email this question. thanks jpd
