Automatically sorting some "cells"

[hsw28]

Hi,
I have, purposefully, a lot of false positives after cell extraction (if I don't it misses things). When I go to manually sort, though, I find myself ALWAYS rejecting, for instance, cells that have an image correlation of <.1-- but it still takes a significant amount of time to click through and reject these as cells. Is there a way to just auto reject these so I have less to manually sort?
Thank you!!
