We use the time-tested method of creating a grid of the array on a sheet of paper and using highlighters in different colors. This was the BASIS for REDESIGNING TARP2 into units of 25 (5x5)—so a unit could easily be visualized with a 4x objective and did not require spot counting to determine exact location. We mark spots as ABSENT, unreadable, and based on whatever grading schema we are using (positive versus negative [0 to 4+]). Scoring is RAPID and provides a PERMANENT record that is easy to track.
