Hello everyone,
New to Slicer - primarily interested in using it for DTI for now.
I have downloaded dMRI and am going through the tutorials with no issues. However, I would like to draw the ROIs for tractography using T1 from the same scan.

I have tried following the tutorial by Sonia Pujol. At the step where I draw the ROIs, I diverage a bit and load the T1 sequence. It was taken during the same scan as my DWI dataset, and looks like it is coregistered with no issues when I scroll through it.

My question is, is it actually coregistered or should I proceed by coregistering my T1 to DWI first, then generating my DTI maps and load the coregistered T1 to draw my ROIs?

Many thanks,
