Dear All,

This probably a newbie question, so I apologize if it is a naive one, please bear with me.

I have on value for each ROI on the surface of brain and one value for each sub-cortical structures. Those ROIs and sub-cortical structures correspond to freesurfer atlas.

I have three questions:

• I am not sure which freesurfer ATLAS these values correspond to? Is

there any way to tell from the name of structures? I have attached two text files including the header of the tables.

The aseg corresponds to the RB_all_2008-03-26.gca (see Fischl's 2002(?) Neuron paper), the other corresponds to the Desikan/Killiany atlas.

• How can I visualize those values on the inflated brain? Something

like this:

http://pysurfer.github.io/examples/plot_parc_values.html

This package is a great but unfortunately very unstable (at least on my laptop). It visualizes the brain but crashes immediately! No time to save the results. Is there any MATLAB equivalent?

• What is the best way to visualize the values for the subcortical

structures?

We don't have a good way to get ROI values back into the volume or the surface. I'd probably do it in matlab doug

Any comment is highly appreciated,

Again, I am sorry if those are naive questions.

Thanks,
