Note:

Total, the total number of metabolites in targeted metabolic pathway; Expected, one parameter; Hits, the actually matched number from the user uploaded data; Raw p, the original p-value calculated from the enrichment analysis; FDR, the p-value adjusted using False Discovery Rate; Impact, the pathway impact value calculated from pathway topology analysis.
