[ccp4bb] Twinned data and maps

Hi again, Thanks for your insight into refinement tools for twinned data. I have a couple of twinned data sets that are nearly perfectly pseudomerohedrally twinned. I've begun to refine my data in Refmac5 (using the automated twin refinement), CNS (using the twin inputs) and Shelxl; I'm testing

Re: [ccp4bb] Twinned data and maps

I am not sure if there is any way of avoiding model bias if the coordinates are included regardless of whether there is twinning or not - my preferred method is to set the occupancies of suspect regions to 0.00 then do refinement of the better parts of the model and then check maps again and
