I am having the same problem with my head modeling, unfortunately. I use Windows 8, 64 bit. I installed the latest version of the Brainstorm yesterday and downloaded OpenMEEG manually as it was recommended here (https://neuroimage.usc.edu/brainstorm/Tutorials/TutBem#Errors) and installed it from Brainstorm again but it didn't work too. Microsoft Visual C++ 2010 Redistributable Package was installed as well. There is pretty much memory available in the pc at the moment. There is no space within the folder path that might cause any problem as it was indicated here (OpenMEEG bug for head model). So I would really appreciate if you could share your opinions on what might the reason that I am getting this error message, please. I attached a screenshot here but it is pretty the same with the initial message in this thread.
Actually it says “Please consider updating your geometry file to the new format 1.1 …” I downloaded the latest Brainstorm version, I believe it shouldn’t be a problem isn’t it.
Do you think would this indicate to a lack of memory?Because all process work without a problem if I decrease the number of the vertices in BEM surfaces to the lowest number (642) or run OpenMEEG on each layer separately I don’t get any problems on running whole modelling. So it sounds like I am having trouble with the memory, doesn’t it? Do you think making memory adjustments in Matlab would help?
