Reliable tags refers to SAGE tags without ambiguous nucleotide base. Known genes are defined as those that match Unigene clusters with at least one known mRNA; uncharacterized cDNA refers to the full cDNAs from RIKEN, IMAGE, expressed clones or any cDNAs without annotation. Novel tag refers to no Unigene cluster match. Each transcript is covered with an average of 3.6 SAGE tags.
