[chimerax-users] Setting the same sdLevel threshold for several volumes

[Moisés Maestro López]

Good morning, 

I would like to set the threshold of multiple CryoEM Volumes (10-20) at the same time, and I would like to put all of them at the same sdlevel.

I use the command:

volume #1 sdLevel 2

But this only work for one volume, if I use 

volume all sdLevel 2, or volume #1 #2 #3 sdLevel 2

It does not work and the threshold are random. 

In chimera I had a script that I use for doing that but I have not found the way to do it in ChimeraX. In Chimera, I normally called the script with an alias. 



alias ^allsd runscript ~/chimeraScriptSD.py

allsd 3

And the script (chimeraScriptSD.py) was:

import sys
import chimera  
from VolumeViewer import Volume

mlist = chimera.openModels.list(modelTypes=[Volume])

sdlevel = 2

if len(sys.argv)>1:
    sdlevel = sys.argv[1] 

for m in mlist:
	
	chimera.runCommand('volume '+str(m)+' sdlevel '+ str(sdlevel))


But I do not know how to do this in ChimeraX. The key point I do not know how to do is to do a loop that say “for any volume in all the opened volumes”.

Thanks for your help

Moisés
