From: A phylogenetic generalized hidden Markov model for predicting alternatively spliced exons
Alternative and single isoform exon candidates. Four splice sites are shown, one acceptor a0, and three donor sites, d0, d1, and d2, and the begin (B) and end (E) of the input sequence. There are four candidate constitutive exons (Constitutive Exon), three candidate cassette exons (Cassette Exon), and candidate exons with multiple functional donor sites (Multiple Splice Site Exon). See text for a description of the splice types: single acceptor (SA), cassette acceptor (CA), single donor (SD), cassette donor (CD), multiple donor 1 (MD1), multiple donor 2 (MD2), and multiple donor above two in number (MDN).
