Are you doing this on a 4D timeseries? Bet only brain extracts the first
volume unless you tell it to do otherwise.
Peace,

Subject: [FSL] bet2 file size change
Hi FSL users,
I noticed that nii.gz files get substantially smaller (~70MB to ~100KB!)
after bet2. Total voxels seems to remain constant, and the datatype goes
from int16 to float32. Do the non-brain regions really include so much
extraneous data?
Thanks,
Alex
