[Chimera-users] Select density of particular sidechains

To show the density near some atoms, use the zone option in Volume Viewer. Choose "Features… Zone" from the Volume Viewer menu to show the zone options in the dialog, and then with the atoms selected, click Zone to apply the chosen radius value.
Or, you can do the same thing with the “sop zone” command, maybe something like:
sop zone #1 #0:2 3
There are other possible options, see:
The reason you couldn’t do it with “zonesel" is that you can’t select only part of the map; it always selects the whole thing.
I hope this helps,
