Re: [phenixbb] red blobs (Andrea Smith)

Hi Andrea, hmm, did phenix.refine actually use optimize_mask=true ? If you compare the logfiles of phenix.refine (for the default run with opimize_mask=false, and the new run with optimize_mask=true) side-by-side with xxdiff or vimdiff (yes this needs to be run from a command-line) then there should be a difference. Making peace with the red blobs is somewhat unsatisfactory from a technical viewpoint, but probably not relevant from a biological one. I'd guess that the authors of https://journals.iucr.org/a/issues/2024/02/00/pl5035/index.html would be interested to look at your case ... Best wishes, Kay Am 15.03.24 um 08:27 schrieb Andrea Smith:

Hi Kay,

I tried the mask optimization and there is no change in how the final map looks like.

Should I just make peace with it?

Best, Andrea

Hi Andrea,

in your case, phenix.refine seems to fill bulk solvent into volumes that are not actually filled by solvent. It might help to optimize the mask, see https://phenix-online.org/documentation/reference/refinement.html#bulk-solve... "6. Mask parameters".
