Dear MRtrix users
does anybody know a good way to rotate bvecs after correcting for susceptibility-induced distortions in DWI data based on a T1 image?
I have used this script (https://github.com/kathrynalpert/app-dwi2t1-nonlinear) to correct these distortions. However, rotating does not work (based on a FSL-format affine transform matrix).
The script refers to a subscript:
#apply affine reg to bvec
which applies the transformation matrix of the DWI to t1 registration to bvecs. It is unclear to me which subscript was used. I tried to use the rotate_bvecs script of the HCPpipeline
however the output consisted entirely of zeros.
I have tried to find an answer in the mailing list, however, was not succesful. Any help would be greatly appreciated. Thank you very much
