MSMS Spectrum Viewer

A node for displaying annotated MS/MS spectra of peptides based on the Lorikeet.js library (https://uwpr.github.io/lorikeet/). An input table could be generated by joining outputs from peptide search engines of the OpenMS plugin and the corresponding spectra from the input mzML file by the spectrum reference. MzML files can be converted to a KNIME table by the FileToTable node.
