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.

WebThe Log2 fold-change (L2FC) is an estimate of the log2 ratio of expression in a cluster to that in all other cells. A value of 1.0 indicates 2-fold greater expression in the cluster of interest. The p-value is a measure of the statistical significance of the expression difference and is based on a negative binomial test. david risnerWebMar 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. The FDR column gives you adjusted p-value (q-value) for each gene. Compare each q-value with your significance level. Note: FDR and log-fold are two very different thing. Share. Cite. … baywa kelheim
