Hi Stephanie,

Your second statement is more or less accurate. Adding validators won't likely affect the speed much. Starting the clump finding with a cut region to remove the cold cells might do something, although I've never run the clump finder like that.

Hi yt-users,

This is actually a bit directed at the developers of the clump finder. I would like to know if including a validator speeds up the clump finder routine. Basically, if I say via validator that I only want clumps whose minimum temperature is below some value, will that help me speed things up by tossing out clumps that don’t fulfill that criteria early on in the process? Or does it only validate after having gone through the entire clump finding routine (after it has looked for children a bunch of times and reached the max density or variable value)?
