Technique for clean, flickerless lines ?

I’m drawing some data using the limit SOP and the resulting lines when rendered have a strong flicker, aliasing effect that AA sampling in the render node does not seem to fix. I’m very new to the software so I’m not quite sure how to go about cleaning this up. I have used this technique here [url]Drawing lines with particles or geometry - Techniques - TouchDesigner forum to draw the lines.

Not sure what it is without posting an example file, flicking and aliasing are two different things in my opinion. But off the top of my head try turning on/off “Compute Normals” in the Limit SOP.
