Hello,

I would like to apply slice timing correction on a resting-state fMRI scan using FSL's slicetimer. I have already used dcm2niix (version: v1.0.20190902) to derive the json sidecar of the scan which has provided me with the 'SliceTiming' variable (which if I'm not mistaken should be in seconds). 

I just wanted to verify: Would it be ok to create a text file containing the values under 'SliceTiming' and use that as the input to slicetimer's --tcustom flag? I was curious since I believe I read in the command's description that --tcustom is supposed to contain values in "fractions of TR." Or should I just derive new values = each value under 'SliceTiming' / TR and use these as input?

Thank you in advance, and apologies if I should direct this to the FSL forum instead!

Cheers,

Panos
