msarc: Draw Diagrams (mis)Representing the Results of Mass Spec
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
(http://www.uniprot.org/). 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 (http://geneontology.org/), 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.
