TOPUP scans BIDS format




I was wondering if anyone of you has experience with converting TOPUP scans to BIDS format. I know it’s an alternative for a b0 fieldmap scan. Is it plausible to think that I can transfer the TOPUP scans to the Fieldmap folder?

Can someone provide me of an explanation or example of how you did it and what type of parameters I should provide in JSON file?

Thanks in advance!



They should be in the fmap folder, yes. Read the BIDS spec here (ctrl-F for “TOPUP”) about how to format them properly. fmap/*_epi files need to follow the following naming convention:

Thanks for the response!
