There are maybe issues in the ways links are being handled here. FreeSurfer 7.x creates links between certain files, typically lh.pial is not a real file, but a symbolic link to lh.pial.T1.

Different states can result from these successive symbolic link conversions: …

If you still have issues at importing the anatomy folder; could you share the a sample file that causes the issue, to understand what is going on? Upload the file somewhere and post the download links here.

@juliadecker

Best,
Raymundo
