Hi - if you're running a full FSLVBM Then I don't think there's too much point in also running SIENAX? Cheers -------------------- Stephen M.

I have two populations one patient and the other control. I performed fslvbm on both groups and then did randomise to find group differences. I was wondering is it possible to limit the sienax normalized calculations to only the significant regions that were revealed from the fslvbm? In other words I binarized the fslvbm results and I only want to include those voxels instead of the entire brain. > > Thank you, > Jeremy >
