The fondation Imagine, as a partner of the University of Paris Cite and of the Faculty of Medicine, benefits from the support of the Paris-Descartes Bioinformatics Platform to come-along with the scientists throughout their Imagine labeled projects (support for the experimental design planning, data handling and analysis, biological tools for data integration and interpretation).

The bioinformatics Platform collaborates with the Imagine scientists and genomic platform to develop an original pipeline for genetic linkage studies (from raw SNP microarray data to visualisation and annotation of the candidate genomic regions via an interactive web interface). This pipeline allowed the analysis of 50 linkage projects by year.

Since 2009, the Fondation Imagine followed the “next” generation sequencer evolution and acquired severall machines more and more powerful. The increasing amount of data generated by these technologies created new challenging issues to store, analyze, integrate and visualize pertinent information. To reach this goal, we have developed a new original pipeline to analyze resequencing projects. Our pipeline, Polypipeline is based on public tools (alignment, variation finding) as well as an original database design PolyDB (storage and minning data) and finally a new graphical interface Polyweb (interpretation and visualization). Our tool is completely generic and is independant from the sequencing technology used.

Our team participates also to various projects, either relating to sequencing like chip/seq, rna/seq… or more broadly to biostatistics like transcriptomic, pathway analysis… We can also help the researcher during the design step of her/his experiment to optimize the odds of positive findings.

NGS analysis


The bioinformatics platform provides imagine scientists (researchers and doctors) with a complete software suite allowing them to manage, analyze and visualize resequencing data (gene panels, exomes or complete genomes).


This software Polyweb includes:

  • an analysis pipeline (Polypipeline) that relies on

  • most relevant public software and databases to realize

  • sequence alignment, variant invocation and annotation

  • (functional consequence, frequency, associated phenotype...).

  • database developed by the platform (PolyProject) for sample monitoring.

  • two graphical interfaces, PolyQuery and PolyDiag for help in interpreting and visualizing the results.



Our team supports also different types of "-Seq" studies, providing expertise in methods such as ChIP-Seq or RNA-Seq.


More broadly, projects based on matrices (transcriptomics), SNP tables and functional studies (enrichment and channel analyses) are also managed by the platform. 


We take care of your analysis projects from quantification to statistical analyses. We have an Ingenuity license that we make available to researchers on a client station to help you in the biological interpretation of your results. A platform engineer is also available to train you on Ingenuity. We can also help you in the posting of your data on the public repository.

Statistical analyses:

Finally, we carry out statistical genetic analyses of groups of patients, commonly known as "burden tests".
