Hi Stephanie - The arcuate fasciculus is reconstructed when you run TRACULA on your diffusion data, but it is not an ROI. Please refer to the tutorial for how to run TRACULA and how to visualize the tracts:

Hello,

I am running some DTI analyses and can't seem to find the Color LUT number for the arcuate fasciculus. Is there a number assigned for this ROI or another way to identify it?

Thank you,
