[FieldTrip] 'dipoli' headmodel Linux version

[IRENE INCERTI]

Dear Fieldtrippers,
I am a new user of FieldTrip.

I'm working with a Windows system.
I'm currently attempting to perform an EEG source reconstruction with
realistic head geometries. FieldTrip implements the Boundary Element Method
(BEM) for EEG using the foreward ft_compute_leadfield function. However,
this requires that an EEG BEM model will be built with ft_prepare_model
function, where in the cfg.method field, you must specify 'dipoli',
'bemcp', or 'openmeg'. Initially, as I was working with a Windows machine,
I tried using 'bemcp'. Unfortunately, the head model failed because,
starting from 6000 vertices (3000 for the brain, 2000 for the skull, and
1000 for the scalp), it produced a 1000x6000 double conductivity matrix. I
have also read in other discussion list that 'bemcp' may encounter issues
and, in some cases, does not compute at all. I would like to try using
'dipoli', command-line executable or Linux version.

Does anyone have experience with this method? Could you please explain how
it works and what input is required?

Thank you very much for your assistance.

Best regards,
Irene
