1. ParLeS. Shareware for chemometric analysis of spectroscopic data. The software was developed for diffuse reflectance spectroscopy but may be used for other highly collinear data. It has the following capabilities:

1. pre-processes data
2. performs principal components analysis (PCA)
3. performs partial least squares regression (PLSR)

2. ColoSol. Shareware for colour space model transformations. The software was developed for transformations of soil colour. Transformations between the following colour models are possible:

(i.) RGB data to dRGB, XYZ, xyY, CIELUV, CIELAB, CIELCH, Helmholtz coordinates, Munsell HVC and a Redness index and
(ii) Munsell HVC data to XYZ, xyY, CIELUV, CIELAB, CIELCH, Helmholtz coordinates, RGB, dRGB and a Redness index.
