Hi Francois,
Our lab is also having similar issues with OpenMEEG. We are using the spherical and overlapping models for the time being. However it would be really helpful if you could tell us when you think this problem would be solved.
We are working on a new source localization project and it would help to know when OpenMEEG would start working again so we can plan our data analysis’ timeline.
Our OS is Ubuntu 18.04 LTS, we are working on the latest version of Brainstorm using matlab.
So far when we want to use the openMEEG option, either of two things has been happening:
1- either nothing happens and the head model/OpenMEEG continues loading endlessly but with no results. We can also see a matlab error.
To update Brainstorm manually, use the menu Update > Update Brainstorm.
The next time you use OpenMEEG to compute a forward model, the newest version (2.4.1) should be downloaded and installed automatically.
