Negative Control Concept Set Issue

(Matt Spotnitz) #1

Hi Everyone,

Recently, I noticed what may be a technical glitch with selecting negative controls. The concepts that I listed in the “Concept Set Expression” but excluded were used as negative controls in the analysis. It seems as if all concepts listed in the “Concept Set Expression” were automatically used as “Included Concepts” even though they were indicated not to be used. Has anyone else encountered an issue like this? Thanks!
