Hi all,
We wanted to post a quick update on this thread. The synthetic field map algorithm designed specifically for gradient echo fMRI is now published (https://t.co/ZtBGxKXBd1) and available (https://github.com/MASILab/SynBOLD-DisCo). We have made it possible to output the field map directly, and also allow user-defined TotalReadoutTime.
Have you all had successes failures with integrating into fmriprep? If successful, we would love to put a step-by-step guide on our github page (or if anyone has connections we’d be happy to try to integrate directly into fmriprep itself).
Thank you again,
MASI lab team
