Dear Freesurfers,
I am looking for information on how exactly the b-table gets rotated.
1. It seems that eddy_correct runs once with 12 doF, and then the bmatrix gets updated based on this registration. Would you please confirm?
2. I know that my data has negative eigenvalues (most of them seem to appear in the 'halo' around the images), and I would like to save L2, L3 voxel values within tracts in the pathstats.byvoxel.txt file. How may I edit dmri_pathstats to accommodate this? My aim is to identify MD, RD, FA, AD (L1) voxel values that were biased by a lot of noise.
Thank you very much, Best, Barbara
