AutoAR

AutoAR is a set of programs that use the Alternating Regression algorithm for deconvolution of the large amounts of data collected from hyphenated instruments. The result is purified spectra and elution curves for each species present in the sample. A confidence interval of the solution is also acquired. AutoAR is written in MATLAB® 4.1 and the source code of the program is given in the book, Data Analysis for Hyphenated Techniques as well as on a CD-ROM, usable across various hardware platforms, that is in preparation. The CD-ROM also contains data sets for experimentation by the user. To receive further information on the CD-ROM, please contact Mr D. Coleman at d.coleman@elsevier.nl

The deconvolution method used, OSCAR (Optimization by Stepwise Constraining of Alternating Regression), is an original development of Erkki and Ulla Karjaleinen, University of Helsinki.

A QuickTime video is available:
FLY_BY.MOV, a 2 Mb segment of a larger animation that has been made from a collection of mass spectra accumulated from a long chromatographic run on a GC-MS. The data set that was used for the animation is also available in original, numerical form on the CD-ROM.
