<p>Hi,</p>
<p>we tracked the error down to the use of Freesurfer 7 instead of
Freesurfer 6.<br>
<br>
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.<br>
<br>
So, for now, the work around is to use Freesurfer 6.0.1...</p>
<p>Hope this helps.</p>
<p>Best regards,<br>
<br>
Axel<br>

<p class="MsoNormal">This is a long shot e-mail! My name is Nate
Smyk, and I’m working at the University of Pennsylvania in
neuroimaging, and I am having the same issue with Simnibs that
you had reported here:

I saw Axel responded saying Mac Catalina might be the issue
(which I am also running on now). Did you happen to find a fix
for this fseek issue? Any insight would be GREATLY
appreciated!!!<o:p></o:p></p>
