Thanks, I think that I figured it out. CheersJohn On Thu, Mar 21, 2019 01:48 PM, "chimera-users@cgl.ucsf.edu BB" <chimera-users@cgl.ucsf.edu> wrote:
Hi John,
I could not reproduce your problem: I opened a map, started Volume Eraser and moved the sphere, and then used command “ac eo” and it erased the density outside of the sphere. (The “ac” command allows using shortcuts without switching into that mode, but otherwise should be the same as using “eo” by itself when you are in shortcut mode.) <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/ac.html>
Otherwise I can only suggest to doublecheck what Juraj suggests. You can see which map models are present and show/hide them with the Model Panel (open from Favorites menu), and the “active” or “current” map is the one with name highlighted in the Volume Viewer dialog. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/modelpanel.html> <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/framevolumeviewer.html>

Hi John,
this tends to work reliably normally, but sometimes it happens you trick yourself into thinking it's not working, usually when you have multiple densities loaded. Make sure that you:
1) have the right density active when you do the erasing 2) don't have other overlapping densities visible (typically a copy of the same density, since the erasing procedure generates a copy it works on rather than working on the loaded original) Since they are identical, you wouldn't notice that your erased volume has changed.

Hi I was trying to use the volume eraser to remove density outside of a sphere on my em map. When I enabled keyboard shortcuts and then used the shortcut command eo what I got back was an identical copy to the original, i.e. no erasure. If I used es then everything in the circle was erased as expected. Am I missing something?
