You can just specify -noxwin to your prepfold command, if I'm understanding your question correctly.

That will likely be the answer. We'll give it a shot

I just doubled checked and we are already doing -noxwin for prepfold calls and it still doesn't seem to like it
from presto.

Here is the error we get even running with noxwin

Error running pstoimg in prepfold_plot(): No such device or address
Also, I have built presto using Spack as the package manager and included pgplot +X +png as well as latex2html as part of the dependencies
from presto.

Ah I see. This really isn't a presto thing, so -noxwin won't help. After presto successfully(?) generates the .ps prepfold plot, it runs pstoimg to convert the .ps file to a .png using the pnm utilities. Try running pstoimg on its own on one of the cluster nodes. If that fails, then you need to get that working, but I'm not sure what that will take. Perhaps something with your DISPLAY envariable or something like that?

Paul,
Thanks, you basically confirmed what I thought. Mostly I was wondering if
it might be possible to generate the plots using matplotlib instead of
converting things through pstoimg and it sounds like that may not be a
practical solution

Yes, directly generating the plots in a more modern format than .ps would be good (e.g. PDF or PNG), but they are generated in C code that calls PGPLOT to make the plots. This would require some effort to update.

PGPLOT cannot generate .pdf output. It can directly output .png, however, it does not use anti-aliasing, nor can you (easily?) change the resolution, and so the plots look terrible. That's why I output .ps and then (if latex2html is availble) use it to convert nicely to .png.
@aweaver1fandm are the output .ps plots being generated? I suspect that they are, and if so, this error really is effectively a warning that latex2html is not available on the compute nodes. That means that you can always re-generate the .pngs (if wanted) post-facto by running pfd2png.sh on the .pfd.ps files on a machine that hast latex2html installed.
If the output .ps files are not getting generated, then this is a real issue and an error that I have not seen before.

I'll double check that the ps files are getting generated

The ps files are being written. I removed the latex2html packages so we
aren't seeing the errors and the researcher will continue to create the png
version of the plots offline after doing runs on the cluster. That is
what they were doing before. Just thought it wouldn't hurt to check and
see what if anything could be done to generate them in the course of the
cluster calculations. Thank you for all your feedback
