WebDear all, I use edgeR for differential expression analysis on a RNAseq dataset. But I found that edgeR is very sensitive to outlier samples. For example, for one gene, overall the expression pattern is similar between control group and experimental group, but there is one single sample which behaves very differently from the others, then this gene is very … WebMar 25, 2024 · To evaluate the ability of DESeq2 and edgeR to identify DEGs, Li et al.

WebThe edgeR package is an R package very commonly used for RNA-seq data analysis. The package needs to input data about the number of reads for each sample for each gene, … WebedgeR uses the negative binomial (NB) distribution to model the read counts for each gene in each sample [9, 8]. The NB disribution is ideal as it is a discrete count distribution ... Consider two samples Aand Bthat are sequenced to the same \depth", i.e., the resulting libraries have the same number of reads.

Web2. DESeq still uses NB by assuming there is no difference b/w two samples to estimate dispersion. The results are 1. edgeR identifies many genes with very small p-values / adjusted p-value when I used common.disp approach. 2. edgeR gives none significant genes with tagwise.disp option. 3.
