PRIDE associated tools: Practical exercise 1 Juan Antonio VIZCAINO PRIDE team, Proteomics Services Group PANDA group European Bioinformatics Institute Hinxton, Cambridge United Kingdom
Overview … • Submission of data: PRIDE Converter • Visualization of data: PRIDE Inspector: • Review functionality • Charts • Practical exercise 1

DATA SUBMISSION TO PRIDE (Submission-driven resource)
PRIDE Submission Workflow Search Engine PRIDE XML PRIDE Converter Mascot (.dat), Sequest (.out) SpectrumMill (.spo) pep.xml, prot.xml
DATA SUBMISSION TO PRIDE USING 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 PRIDE Converter http://code.google.com/p/pride-converter
Why? Submission made easier: PRIDE Converter http://code.google.com/p/pride-converter Barsneset al., Nat. Biotechnology, 2009
The need for new tool Search Engine PRIDE Converter Mascot (.dat), Sequest (.out) SpectrumMill (.spo) pep.xml, prot.xml • Visualize/Check data • Support for reviewers/ editors • More flexible than the web interface • Initial assessment on data quality
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. http://code.google.com/p/pride-toolsuite/wiki/PRIDEInspector PRIDE Inspector Wang et al., Nat. Biotechnology, 2012
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.

Who can use PRIDE Inspector? • Researchers to check their data before they submit it to PRIDE • Journal’s reviewers and editors in the review process
PRIDE web page: PRIDE Inspector Web Start http://www/ebi.ac.uk/pride
PRIDE Inspector Web Start For each submission (private data), a unique URL is generated and it can be included in your manuscript submission: http://www.ebi.ac.uk:21390/pride/jsp/pages/jnlp/jnlp.jsp?username=review53187&password= - *_3XR8G

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) In this exercise…
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. 1) Converting the .omx OMSSA file to PRIDE XML
DATA SUBMISSION TO PRIDE USING PRIDE CONVERTER
Why? Submission made easier: PRIDE Converter http://code.google.com/p/pride-converter
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. 1) Converting the .omx OMSSA file to PRIDE XML
DATA VISUALIZATION AND ANALYSIS USING 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. 2) Visualizing and analysing the data (PRIDE Inspector)
How does PRIDE Inspector look like? • Fast loading of large mzML and PRIDE XML files.
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) Conclusions
