%description
Toolbox for chemometrics analysis of bidimensional gas chromatography
data. This package import data for common scientific data format (NetCDF)
and fold it to 2D chromatogram. Then, it can perform preprocessing and
multivariate analysis. In the preprocessing algorithms, baseline
correction, smoothing, and peak alignment are available. While in
multivariate analysis, multiway principal component analysis is
incorporated.
