Comparison of biological pathway reconstruction based on MinPath and the naïve mapping approach for selected metagenomesa.

ametagenomes sampled from different environments [17] (-Mic, and -Vir are for microbial and viral metagenomes, respectively, as shown in the table).bmicrobial metagenomes sampled from coral, with the total number of sequencing datasets shown in the brackets.cbased on the KEGG pathways (the KEGG database used in this study was downloaded in Dec, 2008, which has 345 pathways).dbased on the SEED subsystems (we used FIGfams release 6, which has more subsystems than reported in [17], and the total number of subsystems included is 898).ethe two numbers present the total number of pathways (or subsystems) found in at least two of the datasets (e.g., two out of 7 for Coral-Mic), and in at least one of the datasets for each environmental location, respectively.
