Extended Data Fig. 6: Venn-like diagram of the distribution of negative ionization LC/MS1 data points in different steps of the HERMES workflow and XCMS peak-associated points.
From: HERMES: a molecular-formula-oriented method to target the metabolome

a) E. coli and b) human plasma extract. Database: data points that match any m/z from the ionic formula database (including isotopes). SOI: monoisotopic (M0)- annotated data points that are present in an unfiltered SOI list. Inclusion List: data points present in a filtered SOI list (including blank subtraction, isotopic filter and ISF removal steps). Percentages refer to the total number of LC/MS1 data points.
