Hi Roey, I could be wrong, but I don’t think you have to worry about the IntendedFor field in the json file for those specific bold files. If you have the bold data set up with part-mag and part-phase (e.g. rf1-sra-data/code/heuristics-test.py at main · DVS-Lab/rf1-sra-data · GitHub), that should allow future researchers use it appropriately (e.g., for framewise SDC, as discussed here: Multi-echo fmaps: Echo 1 and 2 difference unreasonable?).
Best wishes,
David
