VidjilNet Consortium
Gathering onco-hematological laboratories, research centers, and industrial and institutional partners, the nonprofit VidjilNet consortium is dedicated to:
- sustain and support open-source development of the Vidjil web platform, the underlying Vidjil-algo component, and possibly other software to study immune repertoires, by adapting them to the needs of members;
- provide bioinformatics support and services to the members for these softwares, whether for clinical research purpose or for hematological or immunological research. As of 2025, the consortium provides consulting, training sessions, and support to host, maintain, and certify Vidjil analyses.
Being a member of VidjilNet is an opportunity to participate in a community of professionals in hematology, immunology, oncology, and bioinformatics and to promote open research. Members have the chance to contribute to shaping and enhancing the Vidjil platform, fostering a collaborative effort that aligns with their specific requirements. VidjilNet emphasizes the importance of continuous learning and skill development, empowering their teams with the knowledge needed to optimize their research or clinical endeavors.
The consortium works into a quality approach concerning both software development and testing, the relationship with its members, and ethics on health data processing. Vidjil was awarded an honorable mention at the 2022 Open Science Awards for Open Source Research Software, in the Community category.
VidjilNet is incubated in Inria since 2018, and membership is offered since the end of 2019.
Why join the consortium?
- show your interest in the Vidjil platform, deciding collectively on its major developments and participating in the membership community, both on the user side and on the developer side;
- benefit from member-only services: installation, training and support by a bioinformatician engineer, development of functionalities, remote maintenance of a server or hosting on a shared server, transfer of data and backup configuration.
Inria can also receive donations for the VidjilNet consortium.

2026 Meetings
Vidjil Workshop 2026 2026 workshop took place in Rennes on 12-13 October 2026.
2026 Exceptional General Assembly - 12 October, 17:30-18:30 CET
2026 General Assembly - 6 March, 10:00-12:00 CET
Bioinformatians community We are launching the creation of a community of bioinformaticians working in onco-hematology, with or without Vidjil.
The goal is to identify key resource people to connect with each other, allowing us to progress faster and stronger on our various topics.
The exact form of this community has yet to be defined. If you are in this field or know people who might be interested in joining us, please feel free to reach out.
Feature tour // Open meetings on Thursdays. Every two months, discover Vidjil features during a 15’ talk. Join us at 14:00 CET (French) or 14:30 CET (English) ▶️ Zoom link
