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...

Workflow MassBank to KEGG (1)

Thumb
Workflow that queries MassBank DB to retrieve database identifiers (KEGG, PubChem, InChI) and continue search with them to retrieve pathways from KEGG for given compound identifier,searches PubChem via eutils and PUG, queries ChemSpider for compound information and image. Note: Usage of ChemSpider web services requires a valid security token - receive one by registering at ChemSpider (look at your profile to see your token)

Workflow Warp2D - 2D Time Alignment Workflow (3)

Thumb
2D Time Alignment We describe a new time alignment method that takes advantage of both dimensions of LC-MS data to resolve ambiguities in peak matching while remaining computationally efficient. This approach, Warp2D, combines peak extraction with a two-dimensional correlation function to provide a reliable alignment scoring function that is insensitive to spurious peaks and background noise. One-dimensional alignment methods are often based on the total-ion-current eluti...
