S. pyogenes data: from overview to detail. A Data organization. The S. pyogenes project contains three types of experiments, the biological experiment (PLASMAPROT) containing five S. pyogenes samples treated differentially, the MS Injection experiment (2008-02) containing three MS injection samples for every biological sample and the MS search experiment (E3659) containing one MS search sample for every MS injection sample. Every MS injection sample results in one mzXML dataset and all search samples result in one protXML dataset which is generated from all mzXML files used in the identification run. B Experiment Browser. Data spaces and projects are represented by a tree view, project descriptions appear in tool tips. From experiment names one can link to the detailed view. C Experiment Detail View. In the left panel experiment properties (metadata) are listed. In the right panel samples associated with the experiment are listed. Property types (e.g.Treatment Value) and property type values (e.g. albumin) assigned to the sample type are listed for every sample.
