Do you know if there's a way of recreating one DTI direction volume from the others? We have a DWI data set with 200 directions. 3 of them are just pure noise, and another one has a few slices with 'glitches'. For the moment, we thought about just dropping those directions using Mipav. But is there a way of recreating the directions from a weighted sum of the good directions? In the case of the 3 pure-noise directions it may not add much, but the direction with glitches still has a lot of good data in it...
Thanks in advance for your ideas!
