What are Grail Exon Candidates?
A Grail Exon Candidate is a region identified by the Grail neural network as being a potential exon. Candidates have a begin, end, strand, and frame. They begin with either a start codon or AG acceptor splice site and end with either a stop codon or donor splice site. The candidates are subdivided into clusters, with the highest scoring exon in each cluster clearly indicated. These best exons in each cluster are traditionally referred to as “Grail exons”.
