The stats.maxmem setting won't have any effect here, as it only
determines how much data is read at a time when doing the stats. I
think you may simply be reaching the limit of how much a 32 bit
computer can hold in memory at once for one process. This is only
(2^32-1)/1024^2 Mbytes, so once you have a few deformation fields and
stuff in memory, then this is easily reached. 64 bit computers don't
have this limit.
I'm pretty sure that much of your image is not actually brain, so
maybe you could crop the data to make the file a bit smaller.
Best regards,
