WebJan 13, 2024 · how to interpret log fold change (log2FC) on two cases. just quick bioinformatic question if possible. I did read few papers and could not understand what this log fold change means. to make it simple I have a log2 fold change (log2FC) value 2 between condition A and B. WebIn 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.

Negative antilog FC in a graph makes it so that 1 and -1 on the y-axis will be the same, and y-values in between these will be undefined. WebMar 1, 2024 · The point of DESeq2 is to estimate dispersion for your negative binomial model (because you have counting data). You should use the FDR column.
