How have your processed the fMRI data? If you have beta maps in the
native functional space, then you'll need to run bbregister on a
template from the native space, then run mri_vol2surf, the mri_concat,
then mri_glmfit

Subject: [Freesurfer] FW: Functional group analysis
Dear FreeSurfer team,
I'm working on a functional analysis using FreeSurfer. I've already
preprocessed my fMRI data and now I would like to analyze this data
using mri_glmfit. My input is the prepared beta estimates for the fmri
data (regression coefficients) and two groups (with activated regions
for different muscles in the hand; musculus abductor digiti minimi vs
first dorsal interossei). I do not want to smooth my data.
Which command/step do you suggest in order to implement this data into
mri_glm?
I've experimented with mris_preproc and the creation of a FSGD-file in
the structural analysis in order to implement my data in the GLM.
Best, Silas

Dear FreeSurfer team,
I'm currently doing a functional group analysis using FreeSurfer by
following your tutorial:
https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastTutorialV5.1/FsFastGroupLevel -
in order to concatenate the subjects data into one file you suggest
using the command isxconcat-sess. My questions is; is it possible to
use the command mris_preproc as in the structural analysis in this
step? I simply want to project functional beta-values onto the
fsaverage surface and analyze if there is a statistical significant
difference between two groups (after correcting for multiple comparisons).
Best, Silas
