Re: [ccp4bb] Trying to cut the resolution of the datasets

2012-03-20 Thread Graeme Winter
Hi Pete, A couple of observations with this. I found when doing cell refinement with Mosflm setting a conservative resolution limit *was* very helpful in making sure that the refinement was stable. But then switching back to the full detector area for integration was fine after that. However -

Hi Jacob, Therefore, I was thinking an exposure-dependent parameter might be introduced into the atomic models, as an exposure-dependent occupancy of sorts. However, this would require refinement programs to use individual observations as data rather than combined reflections, effectively

I would like to use this to check an existing ligand. I have the PDB refined according to a cif file, and that cif file used for input to REFMAC and phenix. I dont want to lose the atom names assigned there so is it possible to start GRADE with one of those inputs or do I have to convert it
