PERCH (PEak reseaRCH) is an integrated NMR-software package for 
1D-NMR spectra (for more information, see below).

What is new?

- PERCHIT (PERCH compatible version of NUMARIT for large spin systems)
- DORES (Double resonance simulation)
- A new baseline routine (mixed Fourier and Polynominal terms)
- Improved peak picking and deconvolution routines
- A faster MLD iteration/simulation module

What do I need to download?

There are 2 archives, PERCH1.ZIP and PERCH2.ZIP. If you already have 
downloaded a previous demo version, you need PERCH1.ZIP only. 
Otherwise you need to download both archives. The archives were created 
by PKZIP version 2.04g. You need this or a newer version to extract. 
PKZIP is available via anonymous ftp (remember to retrieve in BINARY mode).
To run PERCH under Windows 3.1 you need VBRUN300.DLL (from ftp.funet.fi in
/pub/msdos/windows/util/vbrun300.exe or from somewhere else).

Extract the archive(s) on your harddisk and follow the setup instructions
in README.TXT if you want to run PERCH under Windows.

What is PERCH? (some more information)

PERCH (PEak reseaRCH) is an integrated NMR-software package for research, 
analytics and education. The spectral analysis and simulation up to 10 spins
is based on the program MLDC (Modified LAOCOON with Dipolar Couplings). MLDC
provides several iterative modes, including the traditional LAOCOON-type,
peak-top-fitting for accurate analysis in presence of line-overlap and a
total-line-shape mode, where no assignments are required. Additionally the 
package offers some powerful tools to prepare the input data required by MLDC 
and for research on 1D-NMR spectra in general, like:

  -     import of spectral NMR data from all major manufacturers,
  -     an effective packing utility to compress data by factors up to 20,
	preserving the complete line-shape information of each single peak,
  -     an efficient peak-picking and peak-top interpolation based on 
	a line-shape and noise analysis (essential for precise spectral 
	analysis), 
  -     a multi-term baseline correction (essential as well), smoothing and
	averaging,
  -     a very fast deconvolution (a couple of minutes for fitting frequency, 
	intensity and line-width for each of 20 lines/1000 spectral points,
	including a 4-term baseline correction) with total-line-shape fitting, 
	a graphical peak editing and constraints features for frequencies, 
	intensities, line-widths and integrals,
  -     a graphical assignment procedure for calculated and observed spectra
	with automatic and manual modes. This is what you always have been 
	waiting for!

PERCH takes advantage of 32-bit code, is running on IBM/compatible PC (386/486) 
and can be accessed from a graphical user interface under Windows or command 
driven directly under DOS.
