Hello dear colleagues!
I ran into a problem when I was trying to compute a head model in Brainstorm. I built a 5-layer FEM mesh with brain2mesh, then added a file with stereo EEG channels, and using these data and the DUNEuro plugin, I compute a head model. I computed head model earlier with another file in another project, but there are some problems with this one.
The following notifications appear in the MATLAB Command Window:

Duneuro doesn't stop running, I waited for a long time, but in the end I had to kill the task via Task Manager.
Could you tell what might be causing it to take so long?
