I am running the last step (-long) for a longitudinal analysis, However, encountering an error message saying: "error: ERROR: number of asegs and norm volumes do not match" for all the subjects I run this time. A similar problem has been reported before as the following link. The answer to the question is 'Freesufer version too old'. I have been following the exact same steps two months ago for my last cohort and it was fine. However, this time all the subjects reporting error messages (attaching error.log). 

My system: x86_64 GNU/Linux

Freesufer version: freesurfer/6.0.0

attached the error.log

Best,
