Package: casper 2.39.0
David Rossell
casper: Characterization of Alternative Splicing based on Paired-End Reads
Infer alternative splicing from paired-end RNA-seq data. The model is based on counting paths across exons, rather than pairwise exon connections, and estimates the fragment size and start distributions non-parametrically, which improves estimation precision.
