After beginning research doing optical spectroscopy on fluorescent
dyes within a physical chemistry group back in 1999, these aspects
turned out to be really annoying:
was tied to the spectrometer hardware. Usually, the spectrometer
control software was able to do some amount of spectral data processing
and analysis after recording, but there was no means to analyze
the data in a separate place (at home, in your own lab at another
department). Often enough, spectra processing was equivalent to
blocking the spectrometer from data acquisition.
There was no
efficient way to bring spectral data from different sources together
within a spectral processing environment. Most spectrometer systems
allowed to export data in some way. Being ASCII type data, you
could import them into Origin, GraphPad, SigmaPlot or even Excel.
However, while these programs were good at general data analysis,
there were no dedicated spectral processing features. Did you
ever try to bring an absorbance and a fluorescence spectrum into
a single plot, do baseline correction, normalize them to their
maxima and zoom around with the mouse? A task at least cumbersome
with Origin or SigmaPlot and a nightmare in Excel, especially
if there were dozens or hundreds of spectra...
Well, we couldn't
afford the GRAMS package from Galactic Corporation, and the software
from ACDLabs didn't know much about optical spectra at this time.
Therefore I took up working on a spectroscopy software tool started
by a colleague (Dr. Claus Vielsack) two years earlier.
Since then, I always kept these four goals in mind while developing
the data from the spectrometer
all sorts of spectra together
analyze multiple spectra at once
useful, or else get out of the user's way
goals were matched enough to provide something useful...
For the new
SpectraGryph (developed in 2016), I also followed tightly this
goals. Actually, a fifth goal could be added:
I always keep
an open ear for the users' needs, resulting in mail exchange with
some hundred individual users year by year. Before starting the
current development activity for SpectraGryph, I initiated an
for most wanted features, that resulted
in over 300 entries. The new Spectragryph software is strongly
influenced by these interactions...
