did you look at the results (eg, the aseg)? Can you send the recon-all.log file?

Hello,

According to the FAQ for earlier version of Freesurfer (maybe 6.x), the instruction is below.

First you must run only -autorecon1 like this: *recon-all -autorecon1 -noskullstrip -s <subjid>*

Then you will have to make a symbolic link or copy T1.mgz to brainmask.auto.mgz and a link from brainmask.auto.mgz to brainmask.mgz. Finally, open this brainmask.mgz file and check that it looks okay (there is no skull, cerebellum is intact; use the sample subject *bert* that comes with your FreeSurfer installation to make sure it looks comparable). From there you can run the final stages of recon-all: *recon-all -autrecon2 -autorecon3 -s <subjid>*

The autorecon1 step works good, however, second step ends with error repeatedly in 7.4.1

Bests,
