Scattered points represent genes: the x-axis is the fold change for the ratio Cas-II-gly treated cells vs untreated cells, whereas the y-axis is the -statistic or Log Odds, where is the probability that a gene has statistical significance in its differential expression. Red dots are thus genes significantly over-expressed after treatment with CAS, and green dots are genes significantly under-regulated after treatment.
