Dear Surf Ice,

Thank you for this fantastic program.

I want to visualize my own customized region/tract.
How can I put the value into the specific region/tract and visualize it?

I tried to change the number in gl.trackprefs(15, 3, 0.5). But, it does not work well for me.

Example.
What if I want to visualize 'posterior limb internal capsule' with 0.73 value and 'superior longitudinal fasciculus' with 0.98 value?

Thank you for your help.

Sincerely,
Kakyeong Kim
