Dear Francois,
I updated brainstorm to yesterday's version, but I still get the same error. I sent you the link to the minimal dataset via private message (for data security reasons).
In order to generate the FEM mesh I select the anatomy view and activate the files, that you find in the minimal dataset. I manually add the iso2mesh-master toolbox to the path (downloaded from https://github.com/fangq/iso2mesh).
- right click on the subject
- "generate FEM mesh"
- select "Iso2mesh"
- select "MershMesh"
- keeping default settings (max tetrahedal volume: 0.1; Percentage of elements kept: 100)
*select OK
The Mesh is then created and saved without any bug, but then I can't open it (see error in my original post). MergeSurf leads to the same problem.
For the automatic installation:
If I do not add the manually downloaded iso2mesh toolbox to my matlab path and i repeat the steps above, I agree to let brainstorm download the latest version of iso2mesh, it downloads, tries to install and then I get the following error:
** Error: Iso2mesh could not be installed in: /Users/yvonnebuschermohle/.brainstorm/iso2mesh/mac64
When I check the .brainstorm folder, I find the iso2mesh toolbox, but it is not properly installed; when repeating the FEM generation now, I get the error:
** Error: Line 117: surf2mesh (line 117)
** Tetgen command failed

** Call stack:

** Error: The FEM mesh generation failed.
** Check the Matlab command window for additional information.

I hope that helps! Let me know if you have further questions!
Best,
Yvonne
