Hello Freesurfer people,
I am following the FSL-Fressurfer tutorial from the June course to look
at my data on both applications. I successfully was able to register my
FEAT output (non-smoothed) to the FS anatomical. My questions are for
the following steps:
1. Is there a difference between resampling individual run COPE's to
a common surface instead of resampling subject-level GFEAT COPE's
(in native space)? If they are equivalent the second option seems
to be less cumbersome when typing the mris_preproc command - is
this a correct conclusion?
2. When I display individual functional runs or GFEAT results over
the subject's surface, I am basically looking at FEAT/GFEAT
results, correct? So when I run a surface_based group analysis
using mri_glmfit how similar/different are these results from
those of a group-level FEAT analysis, assuming that I used a
simple one-sample group mean and fixed-effects for both analyzes?
Thank you.
Estephan
