Extracting statistically differentially expressed genes among groups.
If there are more than 3 groups, textbooks of statistics says you should apply ANOVA instead t-test, which should be applied when you compare 2 groups. After running ANOVA, you can extract genes by p-values or BH FDR corrected q-values.
If you'd like apply more sophisticated test, you can export the table of Processed Signals from Datasheet tab, and have R or other statistical software analyze it. You can import the measurement list of gene IDs and P-values back to Subio Platform.
