[Freesurfer] gcut error

Dear FreeSurfer team,

we are trying to remove dura from the brainmask automatically as described in the SkullStrip tutorial: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/SkullStripFix_freeview

This however resulted in the following error when starting this command: *recon-all-skullstrip -clean-bm -gcut -subjid 15689_T1_fs*

Killed Linux ubuntu recon-all -skullstrip -clean-bm -gcut -subjid 15689_T1_fs4.13.0-36-generic #40~16.04.1-Ubuntu SMP Fri Feb 16 23:25:58 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

recon-all -s 15689_T1_fs exited with ERRORS at Mon Mar 5 03:47:39 PST 2018

Attached is the recon-all.log in case it may be helpful. We also could not detect any similar post in the mailing list.

FreeSurfer version 6.0.0

Thank you and best, Anna
