Dear list, In my structure there are some residues in alternative conformations that I would like to refine. I have mostly run Phenix for refinement but recently, I have switched to Refmac and since I have no much of experience I dig into the ccp4 archive and found some tips from Eleanor Dodson and James Holton.
I am currently running refmac from ccp4i2 (ccp4-8.0.015). In this interface, when you specify partial occupancies group, a table appears where you can set Group ID, chain, from residue, to residue, (atom) and, (alt). In my case, Group ID is always 1 and I cannot change it into a different value, which is contrary to what James shared in his examples (shown below) # typical lysozyme % refmac_occupancy_setup.com <http://refmac_occupancy_setup.com/> 193l.pdb occupancy refine occupancy group id 1 chain A residue 1 alt A occupancy group id 2 chain A residue 1 alt B occupancy group id 3 chain A residue 59 alt A occupancy group id 4 chain A residue 59 alt B occupancy group id 5 chain A residue 86 alt A occupancy group id 6 chain A residue 86 alt B occupancy group id 7 chain A residue 109 alt A occupancy group id 8 chain A residue 109 alt B occupancy group alts complete 1 2 occupancy group alts complete 3 4 occupancy group alts complete 5 6 occupancy group alts complete 7 8 My first questions are - If you do not introduce any value in the table, can refmac recognize alternative conformations from the input pdb and refine them? - Could it be that there issome issue in my setup for running Refmac? No idea about where the mistake is. Any help will be really appreciate.
