Additional file 7.A. marginale genes arranged along dimensions of biological and statistical significance. A volcano plot shows the relationship between the p-values of a statistical test and the magnitude of the difference in expression values. On the y axis the negative log10 p-values are plotted. On the x-axis the log 2 values of the fold changes seen in whole transcriptome comparison. The red lines highlight the cutoffs for genes that were analyzed further. Only genes populating the upper right and left quadrants of the plot under two different statistical tests (Kal’s and Baggerly’s) were chosen. This plot shows results obtained for Kal’s test.
