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 a lymphoid population with dedicated [[][Rep-Seq]] methods and softwares.

The Vidjil platform contains three components. The Vidjil algorithm
process high-througput sequencing data to *extract V(D)J
22 23 24
junctions and gather them into clones*. Vidjil starts 
from a set of reads and detects "windows" overlapping the actual CDR3.
This is based on an fast and reliable seed-based heuristic and allows
25 26 27
to output all sequenced clones. The analysis is extremely fast
because, in the first phase, no alignment is performed with database
germline sequences. 

The Vidjil *web application* is made for the interactive visualization and
analysis of clones and their tracking along the time in a MRD setup or
31 32 33
in a immunological study. The web application can visualize data processed by
the Vidjil algorithm or by other V(D)J analysis pipelines, and
enables to explore further cluterings proposed
by software and/or done manually done by the user.
35 36 37 38 39
The web application can be linked to a *sample, experiment and patient database*
able to store sequencing data and metadata, to run RepSeq software
and to save annotations directly from the web application, with authentication.
Clinicians or researchers in immunology or hematology
can manage, upload, analyze and annotate their runs directly on the web applicaiton.
