I made a ChimeraX fix so labels will not cause problems in no gui mode.  I put this in the daily builds (and eventually in ChimeraX 1.5), but not in the ChimeraX 1.4 release candidate since we are too close to releasing 1.4 to include it.

Your script will work in tomorrow's daily build.

Hi,
I hope you are doing well.
I have a python script, to be executed in nogui mode, which does the following:
              -open a pdb file
-define centroids for specific residues
-draw pseudobonds between specific residues -> I am using the command distance for this purpose

The issue arises when I have to save the session (.cxs) when in nogui mode, I am getting this error:
QGuiApplication::font(): no QGuiApplication instance and no application font set.

I believe it is because of the text labels created by the command distance. So, I included the following in my code: run(session, ‘hide #2.*’) and I can now save the session.

I noticed in the model panel that the pdb file is assigned to #1 and the pseudobond to #2. The text labels are created as a submodel of the pseudobond (so #2.1, 2.2,..), hence why the ‘hide #2.*’

Will this fix always work? Is the model assignment also dependent on the pdb file being opened?

Regards,
Shubham
