1.  Read in some data
=====================

Before anything useful can be achieved, data of some kind must be loaded into
memory from a file:  This is accomplished by selecting READ from the FILE menu.
All file formats accepted by Open Genie can be used, including ASCII(2 or 3
column), and various binary formats (ISIS RAW, NEXUS, Genie intermediate, etc.).
In the case of binary files, you will be prompted for the range of
blocks to read.  To read only one block, ignore the 'To:' field.

Data is stored in Sets, with up to 100 stored in memory at any one time.  A set
contains a complete copy of data, including all individual data elements stored
as labeled entities called fields.  An example of a field would be "plot title"
or "X array".  Sets can be selected, manipulated to create new sets, or 
graphically displayed.  Every file read results in a new set being created.  Sets 
can be reviewed or selected from 'select set' on the SELECT menu.

2.  Select fields
=================

If the data loaded was of a recognised format then various default fields, and
their association to the data selected, will already have been selected.  Fields 
such as x, y, and e arrays need to be defined before the set can be manipulated 
or displayed.  To view or change field selections click the BROWSE button or 
choose 'select data' from the SELECT menu.

3.  Manipulate data
===================

Before or after displaying data, you may wish to carry out some standard Open
Genie operations.  Operations include set arithmetic, unit conversion, and
rebinning.  Each operation results in the creation of a new set, leaving the
original data unchanged.  These can all be carried out via the OPERATIONS menu.

4.  Display data
================

Clicking the PLOT button produces a histogram or line graph depending on the
data.  Other types of plot are available via the DRAW menu.  Titles and labels
can also be added from here if such fields were not set prior to plotting.  The
ZOOM button zooms in on the plotting area.  By right clicking on a blank area
of the plot text can be added.  To change the appearence of drawing objects,
such as axes, markers etc., simply right click on them.  To go back to a
previous picture, choose 'select picture' from the SELECT menu.

5.  Save results
================

The current picture can be saved as a poscript file, or CGM file, by clicking
the HARDCOPY button.  Data sets can be saved in Open Genie, ASCII, or NEXUS
format.
