Hi there - 

I am trying to use surf ice node feature to display the locations of contacts from SEEG electrodes. I am doing this by treating each contact location as a 'node' and loading a .node file.

However, I really want to be able to a) load the contacts in groups (corresponding to electrodes targeting a given structure) with a different color, and b) ideally load the contacts with color intensities that reflect some behavioral or physiological effect.

So far I can only load one set of nodes at a time and they all have the same color. It seems like there ought to be a way to specific color and intensity for each node individually but I can't seem to figure out how to do it.

Any guidance would be much appreciated.
