SCAMP is is a powerful MATLAB GUI developed by Duane Carbon
and Harry Idehara, to inspect large numbers of infrared spectra from ISO.  
It allows one to
quickly and very efficiently intercompare and group large numbers of
spectra.  In the GUI tool, the user can scale, shift and normalize
spectra, measure and record features, make spline fits, annotate and save
spectrum comparisons, move quickly from spectral region to spectral
region, etc.  It's a tool which we have used to great advantage
in our work on the ISO SWS spectra.  SCAMP has allowed us to find
interesting molecular features that have gone unnoticed in all the years
the ISO spectra have been available.  We have tried to make SCAMP very
general so that it can be used on any spectrum dataset, including
laboratory spectra.  We are currently making arrangements for its public
release.
