Thanks Daniel,
I see in the FAQ that for 3dmaskave "The user inputs a mask BRIK specifying which voxels to average...". I'd like to do that, but the only way I can find is by using the draw plugin. What I'd like to do is use actual voxel coordinates (as a text file, included in a command syntax etc.) or, preferably, a group of voxels surrounding a specific coordinate. 3dmaskdump, if I understand correctly, uses a mask criteria. Again, I wish to use "coordinates-of interest", and I don't know How I could prepare such a mask.
Any ideas?
Thanks
