Having trouble getting fMRIprep to see phasdif and magnitude images

[AustinBipolar]

Ok, removed the intended for from the BOLD and still didn’t work. Was just trying to add in both as per this comment in this link…

To test version 23.1.3, I excluded the B0Field from all jsons and included the IntendedFor for AP/PA and all BOLD jsons accordingly. It worked. This also worked with version 21.0.1.

How to set B0FieldIdentifier and B0FieldSource?

Hi, According to this thread (and linked threads), it seems that you just need to link the first echo to the fieldmap files, with either IntendedFor or B0FieldSource/B0FieldIdentifier : I hope you will quickly find what went wrong for your dataset!
