msarc: Draw Diagrams (mis)Representing the Results of Mass Spec Experiments

The output of an affinity-purification mass spectrometry experiment is typically a list of proteins that were observed in the experiment, identified by UniProt identifiers ( This package takes as input a list of UniProt identifiers, and the associated Mascot scores from the experiment (which indicate the likelihood that the protein has been correctly identified), clusters them by gene ontology category (, then draws diagrams showing the results in hierarchical clusters by category, with lines for individual proteins representing the associated Mascot score. The results are in general not publication-ready, but will rather require editing via a graphics editor that can interpret SVG (scalable vector graphics) format. As an alternative representation, the package will also generate tag clouds based on the Mascot scores.
