[caret-users] Viewing multiple functional maps

[Alex Fornito]

Thanks Stephane,
I have actually tried this, but the colouration is not the greatest  
for what I would like. For example, if I select red for one map, the  
colour range goes from black to red, and is not great for visualizing  
the activation blobs. If possible, I would like to try and use the  
same colouring/palettes as are implemented when viewing the metric  
files.
Thanks again,
Alex
