Subject: [External] Re: [Simnibs-discuss] mri2mesh error


we tracked the error down to the use of Freesurfer 7 instead of Freesurfer 6.

mri2mesh uses mris_convert from freesurfer to convert the the freesurfer surfaces to .stl-files. Up to version 6, mris_convert wrote ascii .stl-files; since freesurfer 7, it writes only binary .stl-files. Because meshfix can only read ascii stl-files, it crashes.

So, for now, the work around is to use Freesurfer 6.0.1...

Hope this helps.

Best regards,
