Witryna10 lis 2024 · Step 1: DESeq2 creates a pseudo-reference sample by calculating a row-wise geometric mean (for each gene). Geometric mean is used instead of classical mean because it uses log values. It is hence more robust as it is less influenced by extreme values.

These criteria will be used … WitrynaIf a sample is expressed twice as much as the control (FC = 2), the logFC = 1; one doubling of the gene compared to baseline. So, to answer your question: if logFC = -0.5, then FC = 2 -0.5, or 0.7071, which means about 70% of the baseline, not 50%... 50% reduction in expression would be a logFC of -1.
