noesy-presat 1D on Varian

Hi,

        I'm starting to do some urine spectra on our UI 600. I get pretty
good water suppression, phase and baseline using presat, and have played
around with purging pulses, linear back prediction, etc.

        I would, however, like to try what our Bruker brethren appear to
favour: noesy-presat1D. So I set up a standard noesy pulse sequence with
dm='yyyn' (ni=1, phase=1). The problem is that I get ADC overflow - so I
suppose the water suppression isn't great. (gnoesy gives good water suppn
but the spectrum can't be phased.)

        Any ideas?

Thanks,
        Mike
