A Program to Grapically Despike Raman
PyDespike is a program to graphically process (ie. despike) Raman and
spectroscopic data. Removing spikes in data due
to artificial background fluctuations can be a tedious and
time-consuming process, and
since no other software with these requirements was known to exist,
PyDespike was created to make Raman data processing more efficient.
PyDespike is the brain child of Michael Vance (Department of Chemistry,
Stanford University) and much thanks is given to him for supporting the
development of a scientifically useful project and providing valuable
feedback to the graphical interface of PyDespike in its beta stages. It
was written using python and the python extensions to Qt and Qwt (PyQt
and PyQwt), and thus, is
cross-platform. It has only been tested on Windows XP and Gentoo Linux,
but there is no reason for it not to be supported on any platform with
python, PyQt, and PyQwt.
PyDespike can be cited however you feel appropriate, but I would recommend ONE of the following:
Of course, citation format requirements may vary from journal to journal, so adjust the above suggestions as necessary.

It's probably that not every data file type can be opened with this
since only tab-, space-, and comma-delimited text was needed when this
was written. If you can't open your data, shoot me an email with the
data file and I'll see what I can do.
Also, there has been limited testing aside from a few people, so if you
find a bug PLEASE let me know. I'll try to fix it as soon as possible.
PyDespike is licensed under the GNU GPL with an exception to
dynamically link to the non-commercial versions of Qt and PyQt/sip. As
such, binary executables and source code is freely distributable,
provided you adhere to the terms of the GPL for the PyDespike portion,
and the Qt non-commercial license for Qt and PyQt/sip portions as
(i.e. you cannot sell the windows executable of PyDespike as I have
distributed it and need to repackage PyDespike using the commercial
versions of Qt and PyQt/sip).
Most Linux distributions have pre-built, easy-to-install packages for
python, PyQt, and PyQwt, and may even have most of these libraries
installed. In this case, getting PyDespike to run is as simple as
unzipping the source and executing the main python program. If you
don't want the hassle of downloading python and the libraries in
Windows, there is a pre-built windows executable. Simply unzip and run
from that directory.
