A Java framework for statistical analysis and classification of biological sequences

Sequence analysis is one of the major subjects of bioinformatics. Several existing libraries combine the representation of biological sequences with exact and approximate pattern matching as well as alignment algorithms. We present Jstacs, an open source Java library, which focuses on the statistical analysis of biological sequences instead. Jstacs comprises an efficient representation of sequence data and provides implementations of many statistical models with generative and discriminative approaches for parameter learning. Using Jstacs, classifiers can be assessed and compared on test datasets or by cross-validation experiments evaluating several performance measures. Due to its strictly object-oriented design Jstacs is easy to use and readily extensible.

Jstacs is a joint project of the groups Bioinformatics and Pattern Recognition and Bioinformatics at the Institute of Computer Science of Martin Luther University Halle-Wittenberg and the Bioinformatics group of the Julius Kuehn Institute. Initially the projects has also been developed at the Leibniz Institute of Plant Genetics and Crop Plant Research.

Jstacs is listed in the machine learning open-source software (mloss) repository.

Licensing Information

Current release

You can download Jstacs version 2.0 here.
You find an overview of the new features in the Recent changes.
We also provide an API documentation, a Cookbook, and a Reference card for this release.

Getting started & Cookbook

For set-up instructions, a list of basic requirements, and suggestions for your first steps with Jstacs, please see Getting started.

Since version 2.0, we offer a Cookbook for Jstacs in addition to the API documentation. This cookbook comprises a general description of the structure of Jstacs including data handling, statistical models, classifiers, and assessments. The cookbook is accompanied by a number of Recipes or Code examples that can serve as a starting point of your own applications.

For a quick reference, we also provide a Reference card.
