Spectrino is a spectra preparation utility for "R project for statistical computing" (free & required). It has specialized organization and visualization features for spectra.
Spectrino has visual interface - as Windows application with rich set of features to set a structure and manipulate visually spectra and it is accessible from R as a library with a set of commands for selective extraction of spectral data.
R project statistical software offers powerful facilities for quantitative and qualitative analysis for different types of spectral data - variation analysis, linear and non-linear models, etc.
From other side, all sorts of spectral instruments generate data, which must be formatted and organized for further analysis. Spectrino interposes between these two sides, serving as spectra organizer for the spectroscopists and as a visualization / data-extraction tool for the statisticians.
