Re: [Freesurfer] tksurfer tool "graph marked vertices avg" not active

The next step would be to do a correlation between symptom severity and the clustering. Therefore, I want to do a ROI extraction. The aim is to see whether the severity of symptoms correlates with the degree of the structural brain alterations found.

At least full mc simulation was possible with this tutorial. So, I got some significant clusters and I tried to do a ROI extraction of them. Unfortunately it is not working. Do you see the problem attached to this email?

wow, I don't know if something from 2007 even applies now. What are you trying to do exactly?

Hi Doug,

I am looking at freesurfer tutorial 2007-08-20, pages 152 - 155. I attached the certain pages to this email. Here the command within the tutorial:

"Now select Tools -> Group -> Graph Marked Vertices Avg to update the plot with the data averaged over the selected ROI:" (p. 155).

Thanks a lot!

Katharina

what tutorial are you looking at?
