Hi All,

I am looking for some help. I am working with stroke subject MRIs. For initial processing, I have "healed" the brains by applying the mirror image of the unaffected side.  Now what I want to do is to subtract out only the area in which my lesion overlaps with BA4 (anterior and posterior), and get the statistics for that area only.  I have made all the surface labels, turned the lesion into a label, and even created the actual intersect label, but what I really need to do is take BA4, subtract out any overlap with my lesion label, create a new label with this overlap, and then use the mris_anatomical_stats command line to get the statistics for this area to check the change over time.

I know there has to be a way to do this but I cannot seem to figure it out!!

Thanks,

Stephanie
