I have fieldmap images in BIDS format in my data but fMRIPrep skips fieldmap correction step. I wonder what’s happening in the analysis. Do I conclude that my images are not distorted, then it’s skipped automatically by fMRIprep or there is an error?
This is just saying that the development of SDC routines is no longer in the fMRIPrep repo. fMRIPrep still very much does SDC, but does so by invoking another software SDCFlows. This is similar to the anatomical workflow, which is done by calling another external software, sMRIPrep.
