Help for 'project' program.

'project' projects multi-dimensional data files onto chosen dimensions. All of the points in the 'orthogonal' dimensions are summed over. Thus projecting onto a three-dimensional volume of a four-dimensional data file would involve summing the data in the one-dimensional rows orthogonal to the volume.

The input data file must be blocked.

To run the program type

	project <project script file>

The project script file must have the following format:

	input <par file of input data file>
	output <output (projected) data file>
	par <par file of output data file>	! this is optional
	threshold <threshold for input data>	! this is optional
	project <the dimensions to be projected onto>

and a typical example would be

	input /usr/people/wb104/edl387/edl387_5.spc.par
	output /usr/people/wb104/edl387/edl387_5.proj13
	project 1 3    ! two dims. projected onto, dims. 1 and 3

This projects the data onto the (1,3) dimensions. Hence the projected data set is 2-dimensional.

The threshold is in case you want input data values below the threshold in absolute value to be set to 0.
