Thanks Bob, for now I'll try rendering each color separately and fusing.

I'm looking into plugging into an outside renderer like renderman or something. Maybe writing something a la SUMA (in java?) that can talk to the afni window and output a file that can be rendered. There are some fancy graphics people here. I'll see what they suggest and I'll let you know what I come up with.

As far as trying to steal your best employee, it certainly wasn't malicious - really more of an attempt at forming a lebanese mafia I promise not to ever do it again.

Best,
Souheil
