It retrieves the information from the main protein modification controlled vocabularies and/or ontologies (Unimod and PSI-MOD)Ĭhart library developed using Java Swing and JFreeChart, which provides a way to assess the quality of MS experiments

It implements a set of protein inference algorithms, coupled with the ms-data-core-api data model PRIDE Data Object Model ( ms-data-core-api)ĭata model representation of MS proteomics data with special emphasis in metadata information It contains functionalities shared by different PRIDE Toolsuite libraries such as controlled vocabulary data structures and prediction algorithms of peptide/protein properties Table I Organization of the PRIDE Inspector Toolsuite modules In addition, new functionalities were developed for improving the data visualization, validation, and quality assessment. We then extended the original scope of the PRIDE Inspector tool by supporting the new PSI standard formats mzIdentML and mzTab and the wide variety of mass spectra file formats used currently. To overcome these limitations, we decided to develop a new set of algorithms, libraries, and tools for the PRIDE Inspector Toolsuite, suitable to the evolving needs of the field.

However, the original PRIDE Inspector tool had some limitations in terms of software architecture and supported formats and it lacked some functionality for quality assessment and for quantitative data. PRIDE Inspector has become the de facto visualization tool for PRIDE data for many researchers since at present the PRIDE web interface supports a subset of its functionality. The initial implementation focused on visualizing PRIDE data ( via the PRIDE XML format), although mzML was also supported. The main motivation behind the project was to develop a user-friendly visualization tool for researchers to be able to interact with and take advantage of the growing data available in PRIDE. ) was developed as an open source standalone tool to enable the visualization and validation of proteomics data in PRIDE.

We believe that the PRIDE Inspector Toolsuite represents a milestone in the visualization and quality assessment of proteomics data. The PRIDE Inspector Toolsuite supports the handling and visualization of different experimental output files, ranging from spectra (mzML, mzXML, and the most popular peak lists formats) and peptide and protein identification results (mzIdentML, PRIDE XML, mzTab) to quantification data (mzTab, PRIDE XML), using a modular and extensible set of open-source, cross-platform libraries. The increasing use and popularity of the new Proteomics Standards Initiative (PSI) data standards such as mzIdentML and mzTab, and the diversity of workflows supported by the PX resources, prompted us to design and implement a new suite of algorithms and libraries that would build upon the success of the original PRIDE Inspector and would enable users to visualize and validate PX “complete” submissions.

Within the Consortium, PRIDE is focused on supporting submissions of tandem MS data. The ProteomeXchange (PX) Consortium has been set up to enable a better integration of existing public proteomics repositories, maximizing its benefit to the scientific community through the implementation of standard submission and dissemination pipelines. 1 The abbreviations used are:MassIVEmass spectrometry interactive virtual environmentMCP Molecular and Cellular ProteomicsMSmass spectrometryPRIDEProteomics Identifications (database)PSIProteomics Standards InitiativePSMpeptide spectrum matchPXProteomeXchangeXMLextensible markup language.
