The scout is a short, low resolution scan used by the scanner operator
to set the field of view for later scans; it is not use ful.
The SpinEcho looks like it is part of a functional or diffusion sequence
to perform B0 distortion correction (so not used in the anatomical analysis)
I don't know
I have a rookie question regarding free surfer after going through the
excellent course on youtube
First time I know the free surfer does the reconstruction on the anatomical
scan (eg., T1t1_mprage_sag_p2_iso.nii)
I see 3 other files in my data that were never used in the tutorials
