I tried out fmriprep on a single subject’s dataset (using singularity, version 1.0.0-rc8), and it gave me the following warning for each functional run:
“workflow WARNING: No fieldmaps found or they were ignored, building base workflow for dataset”
I have fieldmap (phasediff, magnitude1 and magnitude2) and the dataset passed the BIDS validator (using the online version, fieldmap was explicitly listed there as an available modality). Any ideas what might have gone wrong? I am new to BIDS and fmriprep, so it might be something trivial…
I uploaded the fieldmaps (in sub-sid000522/fmap/), the fmriprep output log and the html report here:
Apart from this issue, fmriprep worked as expected. This tool is great, thanks to all its developers / contributors!
