Overview of the trieFinder workflow. In step 1, each of the selected sequence databases, RefSeq, UniGene, and genome in this case, is scanned and all potential DGE tags in each database are identified. In the second step, these potential tags are merged into a single database of tags, db_tags. In step 3, the experimentally-determined tags are mapped to the db_tags database using a prefix tree. The net result is an annotation of each experimentally-determined tag with respect to the RefSeq, UniGene, and/or genome databases.
