I’d say a booleanized version of the brainmask.mgz would be a better candidate… That is, if you insist on using freesurfer derived data for the creation of the mesh :). (I have no experience with that, and would be curious to hear back what happens if you’d
do so).

Hi JM,

<div class="">Ah…make sense. So one could use the filled.mgz file right?</div>

<div class="">Hi T,<br class="">
<br class="">
I think that you’d need as ‘brain’ mesh a shell that describes the inner surface if the skull/dura (which is the mesh we typically get (with our T1w images) using the summated probabilistic segmentation of gray/white/csf compartments). As such using the cortical
meshes is not correct. Thos should be used for the dipole locations.<br class="">

Dear all,<br class="">
<br class="">
I am trying to compute BEM head model using ‘openmeeg’ . I am working with 3 meshes (figure attached). The brain mesh is actually the concatenated L and R hemispheres. Ft_prepare_headmodel throws an error, correctly so, referring to the fact that there is
still space between the hemispheres. <br class="">
<br class="">
Does anyone know how to process the (red) brain mesh such that it becomes one entity?<br class="">
<br class="">
Any hints much appreciated<br class="">
Thank you<br class="">
Tzvetan<br class="">
