RE: Siemens fieldmap sequence doesn't yield a magnitude image- dcm2niix conversion issue?
Please see my notes at
https://github.com/neurolabusc/dcm_qa_fmap
In particular, when acquiring phase maps on a Siemens scanner, you should go to the `Contrast` tab and set `Reconstruction` to save BOTH magnitude and phase images (as shown in the SiemensPDF.png image). I suspect these images were acquired with only `phase` selected.
