Characteristics of the 1000 Largest Clusters
| Clusters matching a GenBank primate sequence (%)[i] | Average no. of contigs per cluster | ESTs assigned to internal priming (%)[ii] | Clusters exhibiting poly(A) sites (no.) | ||||

[i] With a BLAST score of 150 or higher.
[ii] ESTs are considered as originating from internal priming when followed in the contig by a stretch of 6 A’s or more, or by a 10 nucleotide sequence containing 7 A’s or more. Only ESTs that fully align with their corresponding contig (see Methods for details) are considered.
