Dataset statistics

	Acceptor	Donor
Number of events	173 164	169 650
Average number of annotated sites/event	1.158	1.184
Average number of de-novo sites/event	3.744	3.696
Average number of decoy sites/event	22.451	11.877
Average number of negative sites/event	61.443	56.612

Note: Each splicing event or training example consists of multiple putative splice sites each belonging to one of four types. Annotated sites are found in the Gencode v19 genome annotations. De-novo are not annotated but have RNA-Seq support in GTEx. Decoy sites have a MaxEntScan score greater than 3.0 but are not annotated and have no read support. Negative sites are random genomic locations.
