Hi Doug,

I already loaded a text file of my corrected results from the Monte Carlo Cluster Simulation which reports 15 Clusters (attached picture).

There is another file ending with .mgh and the tutorial says that this is the overlay (clusterwise corrected map) which I can upload in freeview.

In freeview I just have the alternative of uploading a surface or a volume. If I load the file endling with .mgh as a volume I just get a black image with a few numbers on the coordinate plane (attached picture). There is no brain in it.

Is it correct to load the overlay (file ending with .mgh) as a volume or how do I have to load it in freeview?

Thank you so much.

Yours sincerely,

Carina

You should be able to view the map results in freeview just as you would any other map.

Dear freesurfer experts,

we are conducting cortical-thickness analysis using freesurfer-4.4.0 and the final analysis with qdec. I have a question concerning the Clusterwise Correction for Multiple Comparison.

Is it correct that I have to visualize the results of the Monte Carlo Simulation in freeview?

Do I have to upload a special model in freeview before uploading the Cluster Simulation data?

Yours sincerely,

Carina
