[chimerax-users] OpenGL error with nogui?

[Fabian Glaser]

Dear gurus,

I am trying to produce a series of figures on the fly with chimeraX, using a python script of the following format (this is only a simple demo):

test.py:

#!/usr/bin/env python3

import sys
from chimerax.core.commands import run

run(session, "open 1d66")
run(session, "color red")
run (session, "save fig1.png”)

==

This works like a charm with the gui, but without the gui it gives the following error, stops and no figure is produced, we tried both in Mac and linux. We are interest in the —nogui option:

.../MacOS/ChimeraX --script "test.py 1d66" —nogui


Executing: surface sel-residues enclose sel-residues
Executing: transparency 0 ribbons
Set transparency of 542 residues
Executing: ~select
Nothing selected
Nothing selected
Executing: save fig1.jpg
Unable to save images because OpenGL rendering is not available


So is this solvable? How?

We tried also with the —offscreen, no luck either.




Best,

Fabian
