VDJtools is an open-source Java/Groovy-based framework designed to facilitate analysis of immune repertoire sequencing (RepSeq) data. VDJtools computes a wide set of statistics and is able to perform various forms of cross-sample analysis. Both comprehensive tabular output and publication-ready plots are provided.

The main aims of the VDJtools Project are:

* To ensure consistency between post-analysis methods and results * To save the time of bioinformaticians analyzing RepSeq data * To create an API framework facilitating development of new RepSeq analysis applications * To provide a simple enough command line tool so it could be used by immunologists and biologists with little computational background
