Signal-to-noise estimation
Hello! I am new in "NMR world". I have some basic questions regarding the NMRPipe. I would like to know if there is a manner to estimate the signal-to-noise

[Question from NMRWiki Q&A forum] poor signal to noise on 1H-15N heteronculear NOE
poor signal to noise on 1H-15N heteronculear NOE
I have recently attempted to run a 1H-15N heteronuclear NOE experiment in vnmrj (700 rt probe) using the standard sequence that comes with biopack, the signal to nose im getting compared to my standard HSQC is significantly reduced, is this normal? I do not recall this being the case when I ran this previously on a bruker 600 with RT probe? is this normal or does this suggest something is miss set? Also in the no NOE experiment I get very broad noise in the centre of my spectrum/water line.
regards
Tom

Signal enhancement in protein NMR using the spin-noise tuning optimum
Abstract We have assessed the potential of an alternative probe tuning strategy based on the spin-noise response for application in common high-resolution multi-dimensional biomolecular NMR experiments with water signal suppression on aqueous and salty samples. The method requires the adjustment of the optimal tuning condition, which may be offset by several 100 kHz from the conventional tuning settings using the noise response of the water protons as an indicator. Although the radio frequency-pulse durations are...
