The MPROJ program calculates a projection along one of the axes. A projection of a 3D spectrum along dimension number 2 will lead to a 2D spectrum, where all the planes in the 3D spectrum have been added together.
The MPROJ program is called as follows (all parameters must be specified on one line):
<Machine ID>mproj <name> <expno> <procno> <disk> <user> <dimension> <cutoff>
The first five parameters define the previously transformed spectrum file on which to operate. The dimension parameter selects the dimension to project. The name of the projected spectrum is created by appending _<dimension> to the name of the input file.
The cutoff parameter is used as follows: If zero is specified, the sum of the points will be stored in the new spectrum. If a negative value is specified, the maximum value found in the slice will be stored in the spectrum. A positive value is taken as a cutoff: Only values greater than cutoff will be added together.
