[galaxy-user] Metagenomics

Hello I am a relatively new user on Galaxy and I had a question regarding "Fetching Taxonomic Information". It is great that I can retrieve all of the hits for each sequence, but I cannot seem to find an option to also provide how accurate of a match it is to the given taxon. For instance, a percentage match. I can access this information in the original file and programmatically retrieve it but, it would be nice if it came in one package so that I can avoide those false hits that have a low percentage match. Can you please provide me with instructions on how to best to retrieve this information (hopefully in a single file)? Thank you Vincent
