About SDCorrection in fmriPrep I have a pair of SE EPI images with reverse phase encoding direction in addition of the RS-fMRI images. How should I set in this case heuristic to be correct regarding BIDS format ?
Same question regarding DTI but I only have one reverse PE direction volume in addition of the 4D dwi files ?
The should go into
fmap - see section 22.214.171.124 of the spec - http://bids.neuroimaging.io/bids_spec1.1.1.pdf#page=28. Remember to set the
IntendedFor field (it’s optional in BIDS, but required by FMRIPREP)
See this answer: Getting data into BIDS format
Thank you @ChrisGorgolewski.
In both cases, fmriPrep will recognize properly these BIDS filenames for the choice of SDC ?
Shall I set manually the IntendedFor field in json file or is there a way of doing this in heuristics ?
FMRIPREP does not process DWI data so only the EPI images will be used.
I don’t know heudiconv well enough, but hopefully someone else will chime in.
@mgxd do you know how would I do ?
@mattvan83 currently this not supported in heudiconv - you will have to add the necessary scans to the JSON file posthoc conversion. This is something we’ve discussed and hope to add in the future
Thanks @mgxd, hope this will be integrated too in next future.
Concerning reverse phase encoding acquisitions, how should they have to be declared in heuristics to be BIDS validated ?
