<div>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">We don’t work with this type of file regularly. The last time I looked into this is actually one year ago judging from the thread on the discussion list that you probably are referring to.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">The ‘fix’ I made back then was in order to address the error for the problematic file that was shared with us. Apparently, your problematic files have problems of a different nature.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">So, I guess that the code is still not robust enough - that is, it still has too strong expectations with respect to the exact content of the files which are not always met - in order to deal with .obj files.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Could you share perhaps one of those problematic scans with us so that we can have a look, and file an issue about this on github:

I have been following the FieldTrip scanner tutorial, which seems to work with most of my scans (20 scans in total), but not for a subset (7 scans). When I try to load the data for this subset of scans, I get an error in the refine function:<o:p></o:p></p>
