VDJsolver 1.0 Server
The VDJsolver 1.0 server is a program that analyses human immunoglobulin VDJ recombination.
The indetification of V and J genes is performed using standard sequencial alignment against databases of
functional VH and JH genes from the
Sequences are aligned to the following model:
where Pxx designates palindromic nucleotide segments, and Nx
N nucleotides upstream or downstream of D. The optimal alignment is
obtained using maximum likelihood to select the best fit of the sequence to the model.
In the fitting all segments except VH and JH may be omitted. The model includes all
conventional germline D segments in the IMGT database (D gene list)
in normal and inverted reading direction.
For details on the model please see Model description
The project is collaboration between CBS and
immunology, University of Southern Denmark.

- Current version:
No evidence for the use of DIR, D-D fusions, chromosome 15 open reading frames or VH replacement in the peripheral repertoire was found on application of an improved algorithm, JointML, to 6329 human immunoglobulin H rearrangements.

Would you prefer to run VDJsolver at your own site? VDJsolver v. 1.0
is available as a stand-alone software package, with the same
functionality as the service above. Ready-to-ship packages
exist for the most common UNIX platforms. There is a
