Teams will now use ballgown to perform differential expression analysis Bioinformatics training: transcriptomics Protocol We will follow the protocol described in Tophat2 bioinformatic protocol published in Nature protocol, 2012 🚀 I’ve learned a variety of visualization techniques for differentially expressed (DE) genes using both DESeq2 (count-based) and Ballgown (FPKM-based) pipelines. Ballgown was not really designed for *gene*-level differential expression analysis -- it was written specifically to do *isoform*-level DE. For DESeq2, you don't need these normalizations, it expect raw counts as input. So it's not a question of StringTie vs DESeq2, but featureCounts vs StringTie. I would like to perform a Differential Expression Analysis. I read that one can expect a How will DGE analysis tools DESeq2 and Ballgown know that they have to analyse differentially expressed genes from diseased samples comparing diseased with normal. e they tend to take more runtime compared to newly updated Tuxedo protocol (HISAT,StringTie,Ballgown) by Mihaela When I run ballgown on my data, I am getting 29 genes that are significantly differentially expressed, however when I use DESeq2 for the analysis, I get 930 genes that are significantly When I run ballgown on my data, I am getting 29 genes that are significantly differentially expressed, however when I use DESeq2 for the analysis, I get 930 genes that are significantly HiSAT2 HiSAT2 is a spliced (or gapped) mapper. Genome Biol 15:550 Li H, Handsaker B, Wysoker A, Fennell T, Ruan I read about DESeq, DESeq2, EdgeR, limma and it looks like if all the R packages would ask for the raw counts.
