WitrynaIn your case, if a 1.5 fold change is the threshold, then up regulated genes have a ratio of 0.58, and down regulated genes have a ratio of -0.58. log2FC = log2(B) - log2(A) FC = 2 ^ log2FC. As it says in the linked article, log transformed fold changes are nicer to work with because the transform is symmetric for reciprocals.
