-the expression level of alternatively spliced genes from RNA-Seq data, and
-identifies differentially regulated isoforms or exons across samples.  By
-modeling the generative process by which reads are produced from isoforms in
-RNA-Seq, the MISO model uses Bayesian inference to compute the probability
-that a read originated from a particular isoform.")
