This is a great question and I've been searching for the answer myself. Here is what I've come up with: 1) take the log of the fold changes (on the 0 to infinity scale); 2) average the log values; 3) calculate the anti-log; 4) then transform to +/- values if necessary. In your second example: log (0.8) = -0.09691. log (1.25) = 0.09691.

Interpretation: The calculated fold change represents the magnitude of change between the two values, providing insight ... Dividing the new amount. A fold change in quantity is calculated by dividing the new amount of an item by its original amount. The calculation is 8/2 = 4 if you have 2 armadillos in a hutch and after breeding, you have 8 armadillos. This means that there was a 4-fold increase in the number of armadillos (rather than an actual multiplication). So, I want to manually calculate log2 fold change values from DESeq2 normalized counts. So, I am using log2(DESeq2norm_exp+0.5)-log2(DESeq2norm_control+0.5) for calculating log2 fold change values. I am not sure whether it is a good idea or the choice of pseudo-count here is very critical. Any …The ΔΔct method estimates fold change in gene expression data from RT-PCR assay.
