+splicing} (ASAS) from RNA-seq data.  Unlike conventional approaches that
+detect ASAS events one sample at a time, PAIRADISE aggregates ASAS signals
+across multiple individuals in a population.  By treating the two alleles of
+an individual as paired, and multiple individuals sharing a heterozygous SNP
+as replicates, PAIRADISE formulates ASAS detection as a statistical problem
+for identifying differential alternative splicing from RNA-seq data with
+paired replicates.")
