WebAfter the \code {DESeq} function returns a DESeqDataSet object, #' results tables (log2 fold changes and p-values) can be generated. #' using the \code {\link {results}} function. #' Shrunken LFC can then be generated using the \code {\link {lfcShrink}} function. #' All support questions should be posted to the Bioconductor. WebThe DESeq function runs a couple of processing steps automatically to adjust for different library size and gene-wise variability, which you can read about in the DESeq2 vignette. The counts that we have obtained via sequencing are subject to random sources of variation.
