External Email - Use Caution        

Hi Tim,


yes, exactly something like subfigure B but if possible without the colorcode (i.e. some regions yellow and some others in red) having just one value.


This is because it would not be super correct to use a "summary measure" that doesn't take into account the time and the different frequency bands.


Thank you very much for your help.


Best,


Valentina

Hi Valentina,

Just to be sure I get what you are asking: do you want a visualization like subfigure B in this image?

So you have one value per Desikan atlas region that you want to show?

Best,

Tim
