In this session, we walk through a gene-level RNA-seq differential expression analysis, as well as a differential exon usage analysis, using Bioconductor packages. Bioconductor has many packages supporting analysis of high-throughput sequence data, including RNA-seq. The packages which we will use in this tutorial ...
