I’m a new with afni and making MT Roi for mvpa. I got contrast map with functional localizer and afni’s 3dclust (in GUI) clusterized MT and V1 together in each hemisphere.
I want to use just MT not V1 but I think it requires another way to separation over adjusting threshold. How can I do this? Appreciate if you instruct also how I can merge two MT in each hemisphere in one mask.
After this, I’m planning to select top n voxels in that ROI for further analysis. I searched it and I think 3dcalc and 3drank are used. Can I know how the precess is?
