OpenMEEG error #1 and error memory allocation failed

1

Hi everyone, i just try too run the new version of OpenMEEG (with linux system) and i got this error message. (similar to OpenMEEG bug for head model error message but i dont have any space in my location). Previous version of openMEEG was working, is there a big difference between the old one and the new one? if no, maybe i should consider to switch back to the old one?

Thanks!

Humm, seem that i was really out of memory! (sorry about this i should have check this before posting)
But, i still dont understand why it worked previously with same parameter but now it cost about 45gb of ram too run it with and all my cores for a 812v/layer is it normal? (in the past i run the same with more than1922V with no problem with the same computer thats why i am confused)

@Alexandre @sik suggestions?

Got the problem! i really dont know why… but in my MRI folder all my coxtex15000v was deselected and instead I had selected white (dont know if this is clear… but anyway yeah this was impossible to compute anything! so! finally sorry about that this was a fake problem!and i was really out of memory!
