Hello,

This is a known issue with ubuntu16 platforms and other distributions that include perl 5.22. That version of perl is incompatible with the version of the mni tools shipped with freesurfer 5.3

The issue has been fixed in the freesurfer v6-beta release (https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall6.0-beta) and the upcoming v6 release.

Additionally, you can use perlbrew to downgrade your version of perl to v5.20

Hello FreeSurfer Developers,

I'm attempting to compute autorecon1 and everything goes well until mri_nu_correct.mni, where I get the following error:
