Image orientation misinterpretation and gradient correction failures. For the BLSA data, 259 scans had a misinterpreted header with our initial code (A, note the incorrect orientation labels), however the index was able to find the correct vectors to match the image, where vectors are oriented appropriately, but the wrong color (red arrows). Only 2 datasets had failures of correcting b-vectors, both containing severe signal dropout and motion artifacts (B).
