Dear FSL experts,
I’m using the distortion correction tool, topup, for distortion correction of GRE-EPI data.
I have a particular question about the setup of parameters in the config file.
I acquire data with two phase encoding directions and I merge the two volumes then feed into topup as it is advised in the wiki.
However, I want to assume that there was no head-motion between the two volumes and so I wanted to do a simple constrained in-plane estimation of the distortion field, so strictly slice by slice. Is it enough to set the estmov parameter to 0 in all iterations and use other default values that are on the b02b0.cnf file?
Thank you in advance.
BW,
Catarina
