[chimerax-users] Troubles when saving a map

[Stéphane ROCHE]

Dear Mr/Mrs,



I am new to ChimeraX (v 0.7) and I have a trouble when saving a map.



I am working with a .ccp4 map from an electron microscopy project. I would
like to slightly change the pixel size that was inaccurately estimated
during data processing and chimeraX seems to be the program for doing
that.

-          Opening the map is fine.

-          Then I change the pixel voxelsize which is also fine.

-          I then save the modified map (I use the .mrc format here given
that I do not find a .ccp4 format).

-          However if I then use the map with my usual softwares (phenix,
coot) it looks like pure noise. But the map looks normal with some other
softwares (e.g. pymol). I also have no problem usually with my .mrc maps
with any software so I would assume the problem is with the .mrc map I
created



Do you know what I could do to solve this problem ?



Thanks,
