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?
