I am trying to use UCSF Chimera to analysis cry-EM density maps. I would like to read a density map (for example: a .mrc file) in python script and get the array (or a three dimensional matrix) of all voxels of this density map. How could I realize this?

By the way, I tried to learn some basic chimera functions which can be used in python on this website:

However, it seems this website can’t be opened and it shows me a blank page.

Best,

Huiya
