If I have a rather complicated question regarding Topup, SpinEcho Fieldmaps with AP / PA phase encoding directions, who would you suggest I contact?

I have some data that i'd like to send. We obtained GE and SE AP and PA scans, and although SE AP/PA combination pair is recommended, for our case GE AP/PA seems to work better. We're not confusing this with the dual-echo B0 Fieldmaps.

Thanks and best wishes

Johan
