This might be a problem with .mat files, Analyze header file origins
and MRIcro. My guess would be that if you did an SPM checkreg with
the original structural and the ROI image that you saved from MRIcro,
they would also not line up properly.
If that is so, you could try this:
M = spm_get_space('original_structural.img');
spm_get_space('roi_image.img', M);
and then reimport the ROI as above.
Best,
Matthew
