Dear ChimeraX Admin.,

Hello, I was hoping for some help on the save function for an electron-density map (.mrc file).  I have a density map (#0) that I trim using:

vop zone #0 nearAtoms #1 range 6

Essentially, I want to remove all the electron density that is not close to my structure (.pdb) #1.  Anything farther than 6 angstroms disappears, as expected.

However, when I proceed to do:

save newmap.mrc #0

I get the original map with the electron density I don’t want anymore.  It doesn’t seem like I can save the changes to the map, even though I see the changes in the interface.  It seems to want to save everything, ignoring the vop command.  Is there something else I’m missing here?

Thank you for your help,
