we are currently limited to 256^3, which fits pretty much every brain
I've ever seen. What is 310^3? This is on our to-do list.

Hi all,
I want to try Freesurfer in object with a physical sizes are (310.00 mm,
310.00 mm, 310.00 mm) but I have a segmentation fault when running the
recon-all, precisely, in stage 2 when running:
mri_em_register -mask brainmask.mgz nu.mgz
/home/samba/user/douiri/dev/freesurfer/average/RB_all_2006-02-15.gca
transforms/talairach.lta
the out put is :
using MR volume brainmask.mgz to mask input volume...
reading 1 input volumes...
logging results to talairach.log
reading
'/home/samba/user/douiri/dev/freesurfer/average/RB_all_2006-02-15.gca'...
setting gca type = Normal gca type
average std = 7.4 using min determinant for regularization = 5.5
0 singular and 1662 ill-conditioned covariance matrices regularized reading
'nu.mgz'...
Segmentation fault
I have done an mri_info on nu.mgz (Fov: 310) and brainmask.mgz (Fov: 256)
and I found that brainmask.mgz ((256.00 mm, 256.00 mm, 256.00 mm)) has a
size smaller of nu.mgz. I would be gratefully if you can tell me what going
wrong with my data.
Regards
