RNA Sequencing - Building a FASTQ to BAM pipeline

Learn how to create a computational RNA sequencing pipeline using free and open source bioinformatics software. We will use the R to download the Saccharomyces cerevisiae genome, transcriptome, and known SNPs from Ensembl and use a publicly available paired-end RNA-Seq data set from the Sequence Read Archive (SRA) to develop and test our pipeline in R. Learn how to trim reads, align them, as well as further steps like duplicate removal and howto use the GATK for base re-calibration.

Next time, we'll make the pipeline more generic, and use it to run several data sets and extract RPKM values from our aligned data for differential expression analysis.
