We demonstrate how one may use seqgendiff in differential expression simulation studies using the airway data from Himes et al (2014). We use seqgendiff to simulate one dataset which we then analyze with two pipelines: the sva-voom-limma-eBayes-qvalue pipeline, and the sva-DESeq2-qvalue pipeline. justin equestrian boot
