Perseus can be used to perform a T-test and visualize the results as follows: Perform log2 transformation of the quantitative values. This plot shows data for all genes and we highlight those genes that are considered DEG by using thresholds for both the (adjusted) p-value and a fold-change. label: The name of species that need to be annotated (default is NULL).
