Abstract: A corrective method is described for processing results of transcriptome experiments obtained by differential analysis includes the following steps: obtaining the results of the level of expression of genes under a reference condition, and calculating the mean level of expression of each of such genes; obtaining the results of the level of expression of such genes under a treatment condition, and calculating the mean level of expression for each of such genes; calculating the modulation coefficient for the level of expression for each of such genes; calculating a p-value associated with each modulation coefficient; and calculating isobar curves of p-value as a function of the mean level of expression of each of such genes under the reference condition; calculating and associating a median modulation coefficient on the isobar curve of each p-value observed. The processing of results of experiments carried out on DNA chips is also described.
