EBI Roadshow Sofia, 12 June 2012 Juan A. Vizcaíno PRIDE Converter Stand-alone tool for creating PRIDE XML files (the format needed for performing a PRIDE submission) It can support a variety of popular proteomics data formats Metadata must be provided using CVs/ontologies. GUI based tool, easy to use

EBI Roadshow Sofia, 12 June 2012 Juan A. Vizcaíno PRIDE Inspector Stand-alone GUI based tool for visualising and doing a initial analysis of PRIDE XML files and data already in PRIDE via the PRIDE public DB instance. Also private review of data is possible. Still under active development (latest version is 1.2.4). At present it also supports mzML. Wang et al., Nat. Biotechnology, 2012

EBI Roadshow Sofia, 12 June 2012 Juan A. Vizcaíno How does PRIDE Inspector look like? Fast loading of large mzML and PRIDE XML files. Direct access to all PRIDE public database experiments. Private user download facility.

EBI Roadshow Sofia, 12 June 2012 Juan A. Vizcaíno In this exercise… You will use the data generated using the OMSSA search engine (imagine that they are the results of your search) You will learn how to use PRIDE Converter (tool for performing submissions to PRIDE) You will learn how to use PRIDE Inspector (tool for the visualization and analysis of proteomics data)

EBI Roadshow Sofia, 12 June 2012 Juan A. Vizcaíno 1) Converting the.omx OMSSA file to PRIDE XML We need to do this: Perform submission of the data to PRIDE Use PRIDE Inspector to visualize and analyse it We will use PRIDE Converter: we need to provide enough metadata to allow the reuse of the data.

EBI Roadshow Sofia, 12 June 2012 Juan A. Vizcaíno 2) Visualizing and analysing the data (PRIDE Inspector) We will have a look at the new results that have been generated using OMSSA. We will browse the metadata, proteins, peptides and spectra. We will have a quick look at the quality charts, generated in order to make an initial assessment of data quality at different levels.

EBI Roadshow Sofia, 12 June 2012 Juan A. Vizcaíno Conclusions Using PRIDE Converter you are able to annotate the data and get it ready for submission to PRIDE Using PRIDE Inspector, you are able to visualize and perform a first analysis of the results. You have learnt some of the variables that can affect the final results of a proteomics experiment (list of proteins)
