From Michael Love (DESeq2) - https://support.bioconductor.org/p/76099/
Batch effects are gene-specific, and DESeq2 fits gene-specific coefficients for the batch term. If you want to get an idea how much batch variability contributes to a PCA plot, I've recommended the following approach on the support site before: variance stabilize the counts, apply limma's removeBatchEffect to assay(vsd), then use plotPCA to plot the residuals.
# Make some simulated data with a batch effect:
dds <- makeExampleDESeqDataSet(betaSD=1,interceptMean=10)
dds$batch <- factor(rep(c("A","B"),each=6))
# VST, remove batch effect, then plotPCA:
vsd <- vst(dds)
plotPCA(vsd, "batch")
assay(vsd) <- limma::removeBatchEffect(assay(vsd), vsd$batch)
plotPCA(vsd, "batch")DASC is an R package used for identifying batches and classifying samples into different batches in a high dimensional gene expression dataset. The batch information can be further used as a covariate in conjunction with other variables of interest among standard bioinformatics analysis like differential expression analysis. https://github.com/zhanglabNKU/DASC
