I am using recon-all command to process some analyze images. But it seems that this command does not work for all .img images. For example, I have an image with the following information:

256x256x124
0.7mm x 0.7mm x 1.5mm
data type: uint8
description:
position:0    0    0
file orientation:
1 0 0
0 1 0
0 0 1

working orientation:
1 0 0
0 1 0
0 0 1

Will the dimension, resolution, and data type all matter in the process?
