Hi Michael, I had the same issue a few months ago. In my experience 4GB was sufficient. If there are constraints on the memory, I think 3 GB should also work.
I also had the same issue with -gcut and FS 5.0. Back then I had tried to figure out what was the minimum memory required since I had some memory constraints. I was running jobs on cluster where each node had 16 cores and 32 GB total memory (that could be divided between the 16 cores). At most I was able to run 12 recons on each node. So the minimum memory required was ~ 2.7 GB (32 GB/12).

Hello, Approximately how much memory does one need when using the -gcut option with FS 5.1? I had submitted 30+ recons to a cluster that alloted a default of 2.5 GB for processes submitted under this particular queue, and all of them aborted with a bad_alloc error at the gcut stage of skull stripping.
Should 4 GB be sufficient?
thanks, -MH
