Hi Sal - This is the command that trac-all will call if you specify field maps, you can see here what inputs it can take: http://surfer.nmr.mgh.harvard.edu/fswiki/epidewarp.fsl

Hope this helps, a.y

Hi, Could someone point me to an example for a sample phase map that tracula can take as input? We do not have a specific sequence for this on our GE system but may be able to output it from some of our 3D GRE sequences.

Best wishes,
