Dear Babak, 

I would like to use the Witelson and Hampel subregions as starting points for a tractography analysis. The first step would be to transfer those subregions to the original T1 image. However, I'm not sure I have enough information in the outputs of yuki to do so. For example, I was not sure whether the midsagittal plane is identified from an original sagittal slice or if interpolation between several slices occurs (eg in the case where the head of the subject is tilted).

Thanks for your help !

Best,
David
