Hi,
I hope all is well.
Was wondering if any of had heard of an explicit minimum number of DTI directions necessary for using odf / hardi modeling ? I have run a couple of data sets of 30 directions (+ 5 b0) through TRACULA, and have run this same data through diffusion toolkit using the hardi / odf model, with reasonable looking results. I was wondering if there was any specific reason why using these models with 30 directions would be considered in appropriate?
Thanks!
