Hi Gaurav, I think this probably needs to be escalated to Jesper, the author of topup, as I¹m not sure why it isn¹t working as well with your GE data as it typically does with our Siemens data. He¹ll likely want your phase up and phase down spin echo images and the acquisition parameters. I don¹t think the issue is the phase encoding direction, as we use AP/PA for a lot of other stuff now (7T, 3T Prisma, etc). The on other thing is if you¹ve got artifacts in the image (e.g. ghosting) that can confuse topup (which is essentially a specialized nonlinear registration algorithm).
Peace, Matt.
