HySpec toolbox


A freeware toolbox for hyperspectral image analysis has been made available. It includes various routines for importing, correcting, segmenting, analysing and visualising data from various origins. A graphical user interface is included for explorative data analysis. The toolbox is work in progress with minor bugs. There will be future additions and changes, but it is already useful for a lot of tasks.

HotPLS toolbox for MATLAB

HotPLSHotPLS is a free MATLAB toolbox accompanying the recently published article “Hierarchically ordered taxonomic classification by partial least squares” in Chemometrics and Intelligent Laboratory Systems. It consists of an example script, the same data set found in the article and all necessary functions to perform the calculations in the article.

The included set of functions can be used in any situation where classification is performed in a fixed hierarchy and where the data are multivariate, e.g. spectroscopic measurements or similar.

For a thorough description of the method and example see:
Kristian Hovde Liland, Achim Kohler, Volha Shapaval, Hot PLS—a framework for hierarchically ordered taxonomic classification by partial least squares. Chemometrics and Intelligent Laboratory Systems, Volume 138, 15 November 2014, Pages 41–47.

Open EMSC toolbox, published February 2014


The open EMSC toolbox is a freely available collection of functions for performing Extended Multiplicative Signal Correction on spectroscopic data. All functions are based on the Saisir data structure for chemometric data analysis. A graphical user interface is included to make the toolbox accessible for users with no or limited programming knowledge. An accompanying paper explaining the basics of the toolbox is under review in a peer reviewed journal.

Included in the toolbox is a complete replication of the tutorial paper of Nils Kristian Afseth and Achim Kohler published in Chemometrics and Intelligent Laboratory Systems in 2012.
