lfcShrink probelm in many 0 count genes RNA-seq data

Hi, Dr love. I post a question about weird MAplot or volcano plot of DESeq2 diff result and also in biostar. ATpoint give a useful answer about too many 0 count genes and prefiltering. It seems that too many 0 count genes makes lfc shrink have a probelm. And I…

weird MAplot or volcano plot of DESeq2 diff result

Hi, every one. I find a werid MAplot or volcano plot of DESeq reuslt. I am wondering whether you can give me some advice. This diff result is from two cell type bulk RNA-seq. I use two specific marker to get these two cell type using Flow cytometer. I alreadly…
