I would guess you are running out of memory, as 512x512 will require 4x the memory of 256x256 assuming the same number of slices.
Peace,
Matt.

Subject: [FSL] FAST4 crash
When I run the VM version of FAST4, 512x512 matrix crashes during the segmentation.
The message on terminal is following:
Terminate called after throwing an instance of 'std::bad_alloc' what(): stqbad_alloc
Aborted
FAST4 does great job with 256x256 datas, but it crashes on all our 512x512 data.
(Data are T1 weighted)
Does anyone know what's going on?
Thank you so much.
