Azara is a suite of programs to process and view NMR data.
See the LICENSE for the terms and conditions of use.

The problem of support still needs to be worked out, but
one statement definitely holds:  no LICENSE, no support.

Files compressed using gzip (ending in .gz) are also available.
The Azara 'release' is considered to be one of the tar files,
azara-2.0-src.tar.Z or azara-2.0-exe.tar.Z (or the .gz versions).

The executables are compiled for Silicon Graphics computers.
It is hoped that you will run the programs on such a computer.
If not, then you will certainly need to re-compile the programs,
and in particular you will definitely need the source code.

See the file INSTALL in the release for more details.

The sample script files were put together by Bill Broadhurst
of the Department of Biochemistry, University of Cambridge.
The Ansig peak picking macros were written by Colin Hardman
of the Department of Biochemistry, University of Cambridge.
Many thanks to them for putting these files together, and for
allowing them to be placed with this release.

Finally, a quick guide to the programs currently available.
[Motif] means that the Motif libraries are needed to compile
the program, and an X server is needed to run it.

process:
	A general multi-dimensional NMR processing program.
	It can be used just to convert unblocked data to
	blocked data, for use in the other programs.

plot2:  [Motif]
	Allows contouring and viewing of (2-dimensional) planes
	from one or more data files, with hardcopy output also
	available.  Also allows (approximate) phasing of
	(1-dimensional) slices (rows or columns) of the planes.

plot1:  [Motif]
	Allows processing and viewing of 1-dimensional data,
	with 'real-time' control over arbitrary parameters.
	Hardcopy output is also available.

contours:
	Contours (two-dimensional) planes from multi-dimensional
	data.  The contours are output in a format suitable for
	use by Per Kraulis' program Ansig.

peak_find:
	Finds extrema in a spectrum, and optionally allows a
	simple parabolic fit of the extrema centers.

peak_fit :
	Fits extrema (magnitude, phase, center and linewidth) in
	a spectrum using process scripts.

combine:
	Combines two or more separate data sets, e.g. by
	adding them together.  Only a couple of combining
	functions are currently defined.

project:
	Projects multi-dimensional data onto chosen dimensions.
	It can also be used to permute the ordering of the
	dimensions of data.  In particular, any 2 dimensions
	of a multi-dimensional data file can be transposed.

extract:
	Extracts (hyper)planes from multi-dimensional data.
	Useful for testing 'process' on smaller data sets.

deflate:
	Compresses data by zeroing all data below a specified
	level (in absolute value), and then using 'run-length'
	encoding.  Can be used as input to Per Kraulis'
	program Ansig.

reflate:
	Uncompresses data compressed using 'deflate'.

slides :
	Allows multiple Postscript files to be combined into
	one Postscript file.

unblock:
	Converts blocked data to unblocked (i.e., sequential)
	data.  This provides a possible route to importing
	data into other programs.
