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.

The Azara 'release' is considered to be one of the tar files,
azara-1.0-src.tar.Z or azara-1.0-exe.tar.Z.

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.
Many thanks to Bill for putting the scripts together, and for
allowing the scripts to be placed in this release.

It is planned to increase the functionality of Azara in due course.

It is also planned to put the help files (or some modified version
of the help files) and the scripts on the Web (accessible using
Mosaic, for example).

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.

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'.

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