The Biodata toolbox for MATLAB

This paper describes “The Biodata toolbox for MATLAB”, a free software toolbox for MATLAB. Biodata is the result of a PhD project in Raman spectroscopy and is available under the GNU Public License 3. It is a system that consequently stores spectra and related data in a single data structure. Biodata provides a framework for straightforward utilisation of preprocessing algorithms that apply existing chemometric models on unknown data. This paper is not an attempt to summarize or review work on the supported techniques, such as 2D correlation analysis, spectral processing or sample identification, but it is rather intended to inform the reader on the existence, functionality and applicability of the Biodata 1.0 toolbox for MATLAB.
