Hi Qi Zhu, sorry for the delay (always a good idea to just repost if a
few days go by). To answer your question, yes you can do a FFx analysis
that way, ie, average the gamma and gammavar across the ROI, then
t=gamma/sqrt(gammavar) and use the DOF from the dof.dat file in the
mri_glmfit output
Hi,
Sorry for posting again. I just want to get the average ces and cesvar
values across subjects (fixed effect) for a specific ROI, and then run
some statistics on them. Can I just average the gamma and gammavar
that in the osgm folder after I ran the voxel-based ffx group analysis
in my group da
Hi everyone,
Is there any way to do ROI-based fixed effect group analysis in
Freesurfer? I want to get the average ces and cesvar (fixed effect) in
a specific ROI. Can I just average the gamma and gammavar that in the
osgm folder after I ran the voxel-based ffx group analysis in that ROI
