Hi,

Sorry for the late reply. I for some reason did not get a mail about this so assumed that noone answered. I am further along my quest but i am struggling with dealing with overlapping ROIs.

I have 18 ROI centers. I use 3dUndump to make 18 ROI masks of radius 10. Because of the large size, there are overlaps. So when i combine them using 3dcalc using formula (a+b+c+d+e+f+g+h+i+j+k+l+m+n+o+p+q+r) and then do 3dNetCorr i end up with 20 columns with codes 1-18 , 25 and 28. Can you suggest how to deal with this? I would still want 18 ROIs in the end.

Thanks
Prateek
