Hi afni experts,

I have a mask that has 9 different values (9 different ROIs) and I wanted to know if there is a quick way to get the number of voxels for each ROI in the mask. I have looked at 3dROIstats and 3dmaskave but I am unclear about the easiest way to get the total voxel count for each of the 9 values in the mask.

I've used:
3dmaskave -drange ROIvalue mask that gives me a voxel count with a useless mean, but I would have to do this for each of the 9 ROI values and I have multiple masks to do this on. Is there an easier way?

Thanks,
Megan
