I have an error numbered 134 when running a headmodel computation.
** Error: OpenMEEG call: om_minverser

** Many OpenMEEG crashes are due to a lack of memory.
** Reduce the number of vertices on each BEM layer and try again.
I'm so cheeky now and would give my answer here as a software developer to the error. ^^
In your error message you can see the Exception: InflateSkip: inflate returned buffer error was ejected.
You can read more about this here: (Frequently Asked Questions about zlib)
In addition I could see in the error message, which was not the newest compiler version of OpenMEEG used.
Maybe that is a reason too.
and futher more i saw on GitHub the entry (error #-1073741819 · Issue #70 · openmeeg/openmeeg · GitHub).
where the are sugesting that you should not have beyond 10'000 Vertixes in Total. (you have 10'000*3)
So i would suggest degresing the vertices on the head mask and inner and outer skulls. Since these can trigger the inflate buffer error in my opinion if they are too big.
Thanks for the suggestion. I am not using Mac but it’s running on Ubuntu.
I will reduce the number of vertices and retry. What I find puzzling however is that the head model computation ran for all other participants (that have similar/same number of vertices). I would appreciate any insight.
