        i gather that the only way to define an "a priori" mask of the molecular envelope in phenix.refine is to generate Fmask and combine those in refinement - is that right? i.e. there isn't a more intuitive way using a mama mask or somesuch to keep the bulk solvent from flattening out parts you think are model, besides the model that is being refined in the first place? -bryan
