Unusual distribution of LogFC in EdgeR (Single cell)

Question

[kvshamsudheen]

I am doing a differential expression analysis using single cell analysis using edgeR and getting skewed distribution of LogFC. Any thoughts on why I am getting the following distribution.

The code for the analysis

dge <- calcNormFactors(dge)

design <- model.matrix(~0+group, data=dge$samples)

dge <- estimateDisp(dge, design = design)
fit <- glmQLFit(dge, design = design)
my.contrasts <- makeContrasts(KO_vs_WT = groupKO-groupWT, levels=design)
qlf.contrast <- glmQLFTest(fit, contrast=my.contrasts)

Can you describe in more detail how you are doing the analysis, and possibly include your code?

Here is the scripts and analysis description.
