The Information-based Similarity (IBS) method was developed to effectively categorize symbolic sequences according to their information content. The method has been fully described and validated (4), with applications to heart rate time series (1), literary authorship disputes (2), and genetic sequences (3).

This toolbox provides an array of MATLAB functions for quantifying the distance (or dis-similarity) between a set of symbolic sequences, and for displaying the results in graphical form such as dendrogram. The type of symbolic sequences can be binary sequences mapping from a time series, written texts of any given language, or genetic sequences.
