Hi Eun Young - Not sure if anyone has a more elegant solution but it sounds like you could split your positive and negative activations into 2 volumes and use the 2 different colormaps for them.

Best, a.y

Hi all,

I'd like to have a freeview color map that has both a red-yellow gradient and a blue-light blue gradient (the typical colors for positive and negative fcMRI correlations) and ideally no color for 0... None of the standard color maps in freeview work well and I can't seem to find one online. Has anyone created one? Or know where I can view the text file for the standard color maps that come with freeview, so I can create one myself?

Thank you! Eun Young
