I calculation the open-meeg headmodel for a single shell MEG-headmodel I get the following error after updating to the latest open-meeg version on macbook os X13.5 and Matlab 2016b. The problem ist not caused by memory issues.
I still cannot use openmeeg on my mac after updating brainstorm. I am getting the attached error. Even downgrading to version 2.2 does not work, because brainstorm wants me to use the latest version.
Using version 2.2 at least worked on a linux server, so I can use this for now.
Sorry, but there is a different error related to this topic that has been there for a while: When I use the batch processing tool for headmodeling with the attached setting I get the following error, when trying to set OpenMEEG options using to edit button.
The error with “org.brainstorm.dialogs.HotkeyDialog” you copied previously was not related to the OpenMEEG version. Could you please try with the version 2.4 of OpenMEEG?
(for this: delete the folder $HOME/.brainstorm/openmeeg and restart the computation).
This is the error from the Mac:
Subscripted assignment dimension mismatch.
Hello Francois, I am having similar issues with OpenMEEG. I have attempted to run a head model on some MEG data with every variable possible and it either runs indefinitely without finish or terminates due to ‘om_gain’ error. Is there any way this will be resolved within the next two weeks? I must give a presentation for my internship at the NIH in two weeks and am relying on this software. If this is not possible do you recommend any other solution for generating a head model. For now I may simply use the overlapping spheres method.Thank you.
If it runs forever, it might be because you selected a source space that is too big. In the subject anatomy folder, make sure the cortex surface selected (displayed in green) is the low resolution one (15000 vertices).
Check also the BEM surfaces, maybe try with less vertices on each layer (try down to 600 for the head, 400 for the inner and outer skull)
I’m trying to reproduce it. Can anyone provide a MWE ?
I’ve run tutorial_epilepsy('/home/sik/Downloads/', '/tmp/report_dir/') and everything works fine.
What happens if you do the equivalent of this linux commands?
❯ cd ~/.brainstorm/openmeeg/linux64
❯ export LD_LIBRARY_PATH=$PWD

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.
May I know what actually happen, by referring to above printscreen shot, may you suggest to overcome the problem. TQ
