[PyMOL] basic trouble viewing electron density maps

[Criss H. <cri...@gm...>]

I am having trouble viewing electron density maps.
Everything works fine if I use the protein 2F67. But with 7B5C, I am
stumped.

fetch 7b5c, type=2fofc gives me an error:

Warning: failed to fetch from
https://www.ebi.ac.uk/pdbe/coordinates/files/7b5c.ccp4
 Error-fetch: unable to load '7b5c'.

If I go to EMDB and download the map file (EMD_12025) and load it manually:

(set normalize_ccp4_maps, 0

load H:/.../emd_12025.map, \emd_12025

isomesh emd_12025_isomesh, emd_12025, 1.0)

The screen is blank and changing levels, etc. does nothing.

But it works in UCSF Chimera. What am I missing?

Thanks.
