Dear Jesper,
We have a Siemens TRIO, and it is only possible to change the phase encoding from A-P to R-L instead of changing the polarity of phase-encode blips (i.e. from A-P to P-A) as recommended in the TopupUsersGuide. Could you help me how to find out that in the acqparams.txt which directions (e.g. 0 1 0; 1 0 0; etc.) represent A-P or R-L for our Siemens data?
Thanks,
Gabor
