Phase correction:

Just wanted to send through more info on that reverse phase correction tool I was told about - it's called Topup and seems to run through FSL - this is their website: https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/topup

This page also seems to give a walkthrough of how to apply it: https://andysbrainbook.readthedocs.io/en/latest/TBSS/TBSS_Course/TBSS_04_TopUpEddy.html

Let me know if you'd like me to try anything to help get it running - i have a bank of participant data with P-->A and an associated reverse encoded A-->P reverse phase functional series that i can put onto the Z: drive for you if you'd like?
