[ccp4bb] refinement of half molecules

2008-10-03 Thread Andreas Förster
Hey all, I have a structure where two (identical) half molecules occupy one unit cell but are shifted by half a unit cell translation. I would like to refine them concurrently with global occupancy for each protein fixed to 1/2 initially (maybe relax that later). Is that possible in refmac

For sure you could do it by these softwares with occ. set to 1/2 (and in case some restrictions need to be released), if what you mentioned were the TRUTH. But before doing this, you may want to check the possibilities of 1) misindexing and 2) twinning. MR solution with 1/2 z translation fit
