Above is my .json file.
I’m trying to run fMRIprep but I’m not sure whether if I have field map information or not.
As far as I know, if I don’t have field map info, --use-syn-sdc will automatically use t1w images as reference image to preform SDC for epi image.(Please tell me if I’m wrong)
It seems like many people in NeuroStars have PhaseEncodingDirection in their .json file.
But sadly, I don’t.
If I want to perform SDC, should I just add --use-syn-sdc in my command? or Am I missing field map information?
Any suggestions would be appreciated.
Best,
