Hi Arnaud,
I also encountered this issue. More specifically, I found the b0 of 7T is actually at a b-value of 15 (and all the b-values fluctuate at a level of 40 b-value deviation).
It's because of dwinormalise's default b0 tolerance is 10. https://mrtrix.readthedocs.io/en/latest/reference/config_file_options.html#cmdoption-arg-BZeroThreshold I sloved the probelm by seting the "BZeroThreshold" to a higher b-vlaue. To achieve that, I created the config file at "~/.mrtrix.conf", within which I put a line of "BZeroThreshold: 20" . This solved my problem. But the drawback it that I need to set it manually.
Maybe we can add a feature in tractoflow, where if user provide specific b0 threshold, tractoflow pipeline will automatically create "~/.mrtrix.conf".
Best, Ziqi
Thank you @Ziqi-Hao for your input, we are working on a brand new tractflow but it will take times to reach a release. We'll let you know.
No b0 found during Normalize_DWI process. MRtrix dwinormalise fail :
