Step 1. Divide the new amount of an item by the original amount to determine the fold change for an increase. For instance, if you have 2 armadillos in a hutch and after breeding, you have 8 armadillos, the calculation is 8/2 = 4. The 4 means that you have a 4-fold increase in the number of armadillos.

Let's say that for gene expression the logFC of B relative to A is 2. If log2(FC) = 2, the real increase of gene expression from A to B is 4 (2^2) ( FC = 4 ). In other words, A has gene expression four times lower than B, which means at the same time that B has gene expression 4 times higher than A. answered Jan 22, 2022 at 23:31.How to calculate the log2 fold change?
