Dear list,
Concerning the usage of flirt with bbr cost function and a fieldmap I was wondering if there is any experience on:
1. how different it is to use the flirt -fieldmap option as compared to unwarping with the fieldmap first and using flirt -bbr afterwards?
(-- and related: How exactly is the fieldmap applied in this implementation?)
2. how the FSL bbr implementation compares to freesurfer bbregister? E.g. if I use the freesurfer segmentation with flirt -bbr, would that give me similar results as bbregister?
