Dear all, I search my question before I post it. I did find similar questions, but didn't find answer. I want to overlay two files with different colors. For example, one is sig1.mgh from cortical thickness, the other is sig2.mgh from area. I want to use tksurfer overlaying them with three colors: red is significant regions of thickness; blue is significant regions of area; green is overlap significant regions of thickness and area.
I tried to use the following command: tksurfer fsaverage lh inflated -annot aparc.annot -fthresh 2 -overlay sig1.mgh -overlay sig2.mgh It just can display sig1.mgh or sig2.mgh, but can't display two together. In addition, I don't know how to control overlap and other regions color. Anyone knows how to do this? Any help will be appreciated! Thanks in advance! Kathy
