It looks the dimensions are 512x512x256.

it may be that one of your voxel dimensions (and hence FOV) is wrong if it looks squeezed horizontally. Can you find out what the original data dimensions were?

if they look squeezed horizontally I would guess something is wrong. What was your original data? Do you have dicoms? On Tue, 18 Jun 2013, Ray, Siddharth wrote:
Oooppss my bad, but do you know why exactly this was? FOV > 256?
Also when I open the orig.mgz file the image was squeezed horizontally.
Bruce, I have no idea why the FOV is so big. It just occured for few of my subjects. (from large data sample)
Will try include flag and see.
Thanks Zeke.

Hello Siddharth,
The error message says "Include the flag -cw256 with recon-all!" So I would recommend giving that a try.
