Hi Murpholino,
You can use phenix.map_comparison map1.ccp4 map2.ccp4 contour_to_match=1.035
This will identify the contour in map2.ccp4 that encloses a volume equal to
that enclosed by the contour at 1.035 (absolute, not sigma value) in
map1.ccp4.
The method is described in Afonine, P.V., Klaholz, B.P., Moriarty, N.W.,
Poon, B.K., Sobolev, O.V., Terwilliger, T.C., Adams, P.D, Urzhumtsev, A.
(2018). New tools for the analysis and validation of Cryo-EM maps and
atomic models. https://doi.org/10.1107/S2059798318009324 Acta Cryst. D74,

All the best,

I want to compare electron density features of map A from protein A and map B from protein B...
Because each map has a different rmsd level...
...what is the best way to compare electron density between maps?
Is there a way to normalize maps or something like that?
