  1. Ratio indicates the number of correctly identified/total number of tests. The performance shows the average time in second taken to complete a query. The base methods are B: BLAST; P: P Distance; E: Edit Distance; D: DNFP. “Included” means that the query sequences are included in the reference database, while “excluded” means that the query sequences are not included in the database when performing the analyses.
