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.
