Hi Barbara:
1. The rotation component of the registration matrix from eddy_correct is
extracted for each DWI and applied to the corresponding gradient
vector.
2. dmri_pathstats is not a script, it's a C++ executable, so to edit it
you have to download the source code, modify, and rec
Dear all,
Do you have suggestions/ideas for me please?
Thank you,
Barbara

Dear F
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
