This issue thread reports DWI image artifacts observed after QCing https://github.com/courtois-neuromod/anat-processing/releases/tag/r20220623.

These are likely related to wrong FOV placement and/or adjust shim volume.

Ah, seems you had already documented these bad FOVs @jcohenadad re: the two outliers in the DWI images - these will be removed in the stats of the book.

The other outlier that needs to be removed is sub-02/ses-001, re: Arnaud's discovery that only 8 directions were acquired; much lower than all other measurements.
