What is PARIS 2.0?

PARIS (Proteomic Analysis and Resources Indexation System) is a suit of software to manage and analyse the data from 2D electrophoresis based proteomic analysis. It stores information about experiments and analysis procedure, allows the user to search and navigate in genomic and proteomic data, supports visual verification and validation of the analysis results, and provides tools for cross multi-experiment and multi-experimenter data validation and exploration.

Based on a 3-tier architecture, PARIS consists of a PostgreSQL based database server, an integrated research engine and a graphical user interface. The database server manages data regarding experimentation, including sample preparation through biological interpretations of the results while passing by parameter settings of used analysis procedure. It also stores information necessary to connect with external genomic and proteomic resources such as GenBank, SWISS-PROT and KEGG.

The search engine analyses the queries formulated by biologist, provides fast, highly selective access to internal and external data sources, and structures the search results. From information provided by the biologist, it defines a search strategy taking into account the availability of local data and external sources, starts appropriate processing, and structures the provided information in order to facilitate its reading and interpretation. An important feature that distinguishes our system from others is that queries implemented in PARIS are not limited in means for accessing the needed entries in the database, and they also discover relations that were not explicitly noticed in the data but can be derived from them.

Based on Java 2D Graphics, the graphical interface enables users to visualize, to compare, and to correct or validate the results of analysis. It provides most of the basic functionalities of an image manipulation tool such as zooming, scrolling, region-of-interest (ROI) selection and image contrast enhancement as well as spot emboss and gradient computing. Other functions give helps to understand the relationships which exist in the proteomic data. The spot where the mouse cursor is over is highlighted, and the associated genomic and proteomic information is displayed. Given a term such as spot, protein, physiochemical characteristics, etc, we can retrieve all gels having relationships with this term, display the gels in a set of windows, and highlight, by using pseudo-colors, particular relationships such as spot matching, deduced spot matching, and matched spots ramification, etc.

PARIS is particularly designed for maximizing the system usefulness. It exploits the Web Services technology and assists the users to formulate their queries . Users can either select queries from a established list or compose queries by combining previous queries. Complex queries can be formulated from elements directly selected on the images and be previewed before being submitted to the search engine.

Getting PARIS

PARIS is an open source, freely available software released under the CeCILL Licence Version 2. To download the different components of PARIS from this site, please refer to the listing on the right of this page.

PARIS has been tested on Mandrake Linux 8.0, Mandriva 10.0, and Windows XP Professional under the following environment: SUN, Java(TM) 2, Standard Edition. We strongly recommend you to use that environment. Although we're not sure its compatibility when working with other operating systems, PARIS should be JAVA compliant.
