Three workflows, together defined as PUTMEDID-LCMS, have been developed using the open source Taverna environment to perform putative metabolite identification based on accurate mass data acquired from liquid chromatography-electrospray mass spectrometry instruments. Three workflows perform the following steps. (Step 1) Generation of a list of pairwise peak correlations required for input to workflow 2 (workflow 1) (Step 2) Annotation of features to group different ion types of the same metab...
