%description
Collection of baseline correction algorithms, along with a framework and a
Tcl/Tk enabled GUI for optimising baseline algorithm parameters. Typical
use of the package is for removing background effects from spectra
originating from various types of spectroscopy and spectrometry, possibly
optimizing this with regard to regression or classification results.
Correction methods include polynomial fitting, weighted local smoothers
and many more.
