Hi,
I have finished the 4.5.0 fsfast tutorial, and am wondering about the structure-function registration part. Currently, the tutorial recommends: fslregister-sess -s mgh-101.1. I notice that a single register.dat is produced. How are the multiple runs being handled now? Is only the first run used or all the runs are automatically used?
I am asking because I would prefer to use bbregister. In bbregister, one passes to bbregister an anatomical subject id and a functional volume. So,
(1) Which functional volume should I give to bbregister? (2) Are the functional volumes of the different runs co-registered after I run "preproc-sess"? (3) Presumably, I should also give bbregister the pre-smoothed, but motion corrected functional volume since smoothing would remove the gray-white boundary distinction that bbregister uses?
Thanks, Thomas
