Hi, Thanks for getting back to me so quickly. I have a network mask (in grey) and the colored areas show voxels that are significant for a contrast within the network. We want to show which areas of the brain are included in the network referenced against the results of the statistical test. My colleague tells me there may be a way to do this in photoshop so I might migrate the images over there if it doesn't work out to do them directly in AFNI.
