[chimerax-users] Show map only around certain selection

[Elaine Meng]

Hi Karim,
You can use the command "volume zone" with "newMap false":
<http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#zone>

For example, if your map is #2 and your atomic model is #1 with chain of interest B, could be something like:

volume zone #2 near #1/B range 5 newMap false

(or "near sel" to use currently selected atoms instead of "near #1/B" to specify the chain directly).  Then to go back to the full map display, command:

volume unzone #2

<http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#unzone>

I hope this helps,
Elaine
