Analysis of Heterogeneous Immune Repertoires with Vidjil

Lille, France, 15-16 March 2016

V(D)J recombinations in lymphocytes are essential for immunological diversity. They are also useful markers of pathologies, and in leukemia, are used to quantify the minimal residual disease during patient follow-up. High-throughput sequencing (NGS/HTS) now enables the deep sequencing of lymphoid populations. With dedicated Rep-Seq bioinformatics methods and software, clinicians and researchers can now qualify and sometimes quantify the heterogeneity of these lymphoid populations.

This workshop was intended for users and developers of Vidjil, to share experience, protocols and results, to raise questions and decide development priorities, and possibly to set up new collaborations between biologists and bioinformaticians. The workshop included two invited talks, hematology, immunology and bioinformatics talks from the users and developers of Vidjil, and practical hands-on sessions on participant data. The workshop gathered 34 scientists from 5 countries.


Program

The workshop will start on the Tuesday at 9:30 and end on the Wednesday at 16:00. For the practical sessions, the participants are invited to bring a laptop and some of their NGS data (fasta / fastq / fastq.gz files). The data can also be uploaded into user accounts on app.vidjil.org before Sunday 13 March. There will be no internet connection in the workshop rooms, but all the data uploaded before March 13 will be available on a local server. We will also provide test data for the people who do not currently have their own NGS Rep-Seq data.
