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.

Surfice only allosws the user to load one set of connectome nodes at a time. You can use a threshold on the color or intensity to only show some nodes and hide others. The simple solution is to write a Python script to concatenate nodes from multiple files as a single file for each image. It is easy to add support for multiple node files, but providing an intuitive user interface is tricky.

The other option is to use NiiVue that allows multiple independent node files.
