That makes sense! I will double-check my metadata. Thanks so much!
Just one last question, could you let me know how I can check whether the direction is opposite or not?
I used HeuDiConv with the ‘-minmeta’ argument to create the metadata files and didn’t manually input any of the fields, so I’m not sure what caused the incorrect PhaseEncodingDirection.
Just checked that the PhaseEncodingDirection of the fieldmap metadata is ‘i’, whereas that of the EPI metadata is ‘i-’.
If you could give me any input regarding it, it’d be really helpful. Thank you in advance again!
