Is there anyone using the MapMan pathway /ontology analysis software ? I am having trouble to understand how are the p-values calculated using the Wilcoxon Rank Sum Test. I uploaded a list of genes (both DEGs and non-DEGs). It calculated p-values for the bins. For one such bin, i noticed that even though the genes were not deferentially expressed, it gave a significant p-value. What could be the possible reason for this ?
