Hi FreeSurfer team,

My lab is looking at longitudinal data across 5 time points for each subject. All of our time points have been edited in version 5.1 for consistency. However, I have run into an issue when trying to create the bases for these subjects in this version due to a memory allocation problem. It appears that 5.1 cannot allocate enough memory to store the temporary files for each of these time points and consequently errors out during the registration stage with this message:

I also tried creating the base using a memory flag (-m) to allocate more memory but had no luck in those attempts.

I tried creating the base in version 5.3 and this ran successfully. However, because this is a longitudinal data set ran in version 5.1, it’s problematic that the jobs crash in 5.1.

Is there anyway to allocate sufficient memory in 5.1?

Thank you,

Allison Rainford
