Thank you so much for the quick reply.
May I ask some additional questions?
1) Can I change the color of the ROI in the picture? As you can see in the picture I attached, I can barely see my ROI, which is in the center of the brain. I couldn't find any parts in the Do_06.tcsh on changing color. Is there any ways to change it?
2) my ROIs for the deterministic tract is orbitofrontal cortex (front part of the brain) and striatum (center of the brain). but as you can see in the picture, my tracts go through striatum and reach all the way back to the occipital cortex. It happens to only few people. should I use mask to these people? :(
Thank you for your kindness
