Hi Elaine, What about hideDust? I was trying to resample a selected surface that had hide dust alterations to it. Would this also only be a display setting too then; therefore, I could not hide dust then resample. That is what I am trying to accomplish, but the alteration does not seem to save.

It’s analogous to opening an atomic structure from the PDB and then changing its coloring…. just a display setting, not an alteration of the underlying data, and these display settings aren’t part of the formats in which the data are saved.

Hi Chimera,

I am having problems saving changes of volume.

Here is my script: • open C:\Users\ Desktop\density.map • volume #0 level 1.0 • sel #0 • volume sel save C:\Users\ Desktop\density2.mrc

This does not save the change at line 2. How can I go about to save the change?

Best, Ryan Harlich

Hi Ryan, Maybe you are actually trying to mask the map with the surface, i.e. delete parts of the map that are inside (or outside) some surface. If so, see command “volume mask.” In general the “volume operations” are commands that actually edit the map, creating a modified copy. Volume operations including masking: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#vop> I hope this helps, Elaine

Hi Ryan, These are all isosurface display changes. The map consists of density values at points on a 3D grid. A map can be shown with multiple isosurfaces, or no isosurfaces at all. None of the map values are changing. Elaine
