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 yourtutorial:
https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastTutorialV5.1/FsFa
stGroupLevel - 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
