COMSPARI is the acronym for COMparison of SPectral And Retention Information. It is a software that has been written to facilitate the analysis of "paired" samples, i.e. samples that are almost identical yet present some qualitative difference. The software was originally written for the analysis of data files produced by GC/MS and LC/MS, but can be used for other techniques, too.
cdf2ascii, included with the COMSPARI package, is probably also of use for anybody that desires to write programs or use existing programs that want to deal with flat ASCII files rather than NetCDF files.
The program is currently (that is, fall 2003) in an early, yet fully operational stage. It has a command-line interface and a simple graphic display based on gnuplot. The program was developed under Linux and should generally compile on any POSIX-compliant platform. In addition, it is also operational under recent versions of Microsoft Windows.
There are some informational files that are included with the distribution snapshots that we are linking to here for quick reference; these are: README, INSTALL, QUICKSTART, LICENSE
We will add some more information, examples etc. as time permits.

The COMSPARI software package depends on several other packages. For "normal" use on a standard Linux system, all you need is gnuplot, a scientific data plotting package and the prebuilt/essentials package.
If you want to recompile comspari or cdf2ascii or if you want to do other development work, you will also need the netCDF library and the ANDI-MS libraryANDI-MS library to access the netCDF data files. You might also want to pick up the GNU readline package.
For convenience, we provide several different compilations for download:
This contains everything that is in the
prebuilt, sample, and required tarballs below,
in one huge file. This is useful if you need to make
COMSPARI work e.g. on someone else's computer without installing any
system-wide software. It is also handy to download if this is your first
time running COMSPARI and you want to get everything set up like we have it.
Download: comspari-current-all.tgz (Size: 16M , comspari-20031215-all.tgz )
contains just the "essential" files (comspari, cdf2ascii,
cdfinfo) and their source code. If you already have COMSPARI
working, this is probably what you are looking for to stay updated. It is very
unlikely that we will be changing the sample or required packages in the
near future. This package assumes that you already have the required libraries
and gnuplot installed.

Sample data files:
This archive file contains
just the two datasets, "ko" and "wt", in NetCDF format. Using
these files, you can
try out the COMSPARI package without generating your own dataset(s).
Download: comspari-current-sample.tgz (Size: 3.8M , comspari-20030822-sample.tgz )
These are packages that we did not write and we
do not maintain. They are provided here as a convenience but you should
consider getting these packages from the original sources.
Download: comspari-current-required.tgz (Size: 11M , comspari-20030925-required.tgz )
The Comspari software is in a fully operational stage. However, the more you use it, the more options come to mind ;-) ... a few of those possibilities are:
Things that are somewhat "unstable" and that should be fixed in the future:
