Dear experts
I was wondering whether there is a way to create an overlapping fixel mask of 2 separate analyses?
Cheers,

Hi Hamed,
To compute the intersection of 2 binary fixel masks, you can simply use mrcalc
, as long as both masks are of course defined for the same set of fixels (i.e. have the same index.mif
and directions.mif
file). If you don’t have binary masks yet, you’d first get them from e.g. your FBA results by applying mrthreshold
with the -abs
option to the relevant FBA output (e.g. the p-value map). Then simply run mrcalc mask1.mif mask2.mif -min intersectionmask.mif
to compute the intersection. Make sure the output ("intersectionmask.mif
") also ends up in a folder with the same index.mif
and directions.mif
files (or copies of them). Similarly, if you’d be after the “union” mask (rather than the intersection), you can use mrcalc
, but with the -max
operator.

Hi Thijs
Thanks. It was exactly what I was looking for.
