I would like to use
qsiprep to preprocess DTI data that I have acquired. I have been able to run it successfully on my data without any errors. However, I notice that the b-vectors after preprocessing seem to be flipped along the x-dimension. This results in incorrect FOD estimations. I was wondering if there is a way to correct this, or if any parameters need to be tuned to rectify this issue.
Thank you for your help.
