+<p>For description of metabolites if the proportional difference of the m/z ratio between Evan's EPFL Polar metabolite assignments and RTI assignments was very low (<.0001 proportional m/z units) then the symbol and description was taken directly from Evan's metabolite file, but if differences were between 0.0001 and about .0003 proportional m/z units then the descriptions were labeled "Putative" . If the differences were greater than .0003 units, then the descriptions were labeled "Provisional".
