WebbIf so, I thought to use the unstranded data for my DGE analysis to reach the final number of 4 replicates per stage. I mapped the raw reads to the genome using TOPHAT (v2.0.9) (fr- unstranded for unstranded data and fr-secondstrand for stranded data), used htseq-count (HTSeq 0.5.4p5) to get the raw reads counts for both the data. http://duke-biostats.github.io/ngs-2015/DESeq2Notebook.html how did tank impact ww1
