Multiple solvent suppresion using shaped pulse is basically performed using the basic simple solvent suppression using shaped pulse parameter set (pulprog zgps) and defining the shape pulse for multiple-solvent suppression (spnam6) purposes.

Define the pulse shape using stdisp by taking the required frequencies from the 1D proton spectrum.

The power level and the duration of the presaturation are defined by sp6 and p18*l6 (p18 is set to 100ms and l6 is the loop), respectively.
