And now you want to do an ROI analysis or a map-based analysis of the
subcortical structures? We don't do the latter as that is a VBM analysis.

Apologies for likely using the wrong term. I meant to say that I've
done the cluster-thresholding for the surface data, using the
mri_surfcluster command with annot -aparc as an argument.

This is what I don't understand: "done the cluster-thresholding for the aparc
data"
The aparc data is an ROI and so you should not have (could not have)
done clusterwise thresholding (?)

Hi Doug,
I'm currently running the LME mass-univariate analysis (I've
previously conducted the LME univariate analyses with ROIs with little
to no problems) and, thanks to your help, have run my data through
this analysis and done the cluster-thresholding for the aparc data but
not the aseg data

Which processing are you doing? It should be obvious if you are doing
Hi Doug,
Thanks for your quick response! When running the LME mass univariate
analysis, I am assuming this also includes subcortical structures,
correct? From my understanding, subcortical areas are segmented as opposed
to parcellated. The main thing I want to examine all the regions of the
You can put surface data back into the volume with mri_surf2vol (which
will also merge left and right into one volume). What do you do with the
aseg data?

Dear Freesurfer Experts,
I have run my participants' longitudinal sMRI data through the
preprocessing longitudinal pipeline, ran the LME multivariate analysis,
cluster-thresholded the data, and am now trying to visualize those results
in Freeview (for some reason tksurfer is very, very slow to
