Colleagues,
One recurring question on this bb is "I got this blob of density - is it
my ligand or what in the name of pink unicorns this is?" Often, a
screen snapshot is posted, which is very helpful. But it may be better
if those helping out could rotate density around in 3D. Understandably,
posting the full model/map is not the way to go. However, I'd see no
harm in posting just a small cutout of the map in the region of
interest. It's not a difficult task (fft/mapmask or perhaps some usf
magic), but is there some user-friendly approach to cutting out a small
map volume? One can use coot to mask the map and then export it, but
this seems to generate the ccp4-formatted map that covers more than just
the masked region, thus the files are fairly large. Does anyone know of
a simple solution other than placing dummy atoms in the region of
interest and running fft/mapmask combination? (Is there
phenix.cut_the_map_around_this_weird_blob ? :)
Cheers,
Ed.
