Hi,
An FSL/Freesurfer newbie question:
We are conducting analyses of functional data extracted to the brain surface
(by Freesurfer), registered to that surface.
I am first performing lower-level FSL analyses of single-subject, single-run
data using the Freesurfer surface functional data (converted back to
Nifti). I always get same error message when I enter the functional surface
input (“Warning – have auto-set BET preprocessing option and/or registration
DOF on the basis of image fields-of-view; check settings”), but I have been
ignoring this message and the analysis seems to run fine.
However, when I try to run a higher-level analysis across sessions using the
lower-level FEATs, I always get another error message ("Registration has not
been run for all of the FEAT directories that you have selected for group
analysis. Please turn on and setup registration”) and the analysis won’t
run. This occurs regardless of whether my lower-level analyses are
registered to the extracted surface structural, to the extracted surface
functional, or with registration turned off.
Searching the FSL list, I see others have had this problem (back in 2005),
but it appears the solution promised at
http://www.fmrib.ox.ac.uk/fsl/freesurfer/index.html cannot be accessed as
that URL is no longer active.
Any suggestions?
Sorry for the somewhat simplistic question.
