Dear support,

I would like to solve some problems that I am encountering in my research.
More specifically:
-When I overlap flair.nii and lesion.nii (obtained from automatic software) in MRICRON, all appear correct. If I convert lesion.nii in voi, it is flipped. Is there a way to maintain the same reference system after conversion?
-When I overlap overlapping map (alllesion.nii) on aal maps, using descriptive statistics, I obtain several parameters (numVox numVoxNotZero fracNotZero peak min mean meanNotZero).Can I have more information about the meaning of each of them?Is there a cutoff within which I must consider the damaged regions?
Thanks
