Hi NMRPipe users, I have a spectrum with a very strong rolling baseline caused by a background material signal. I have tried to use LP to correct the first few

Re: Baseline issues in directly detected proton dimension of 13C-HSQ
Hi Justin, This sensitivity enhanced experiment usually achieves good water suppression, but you could try removing some of the water with a polynomial solvent

[NMRpipe Yahoo group] Baseline issues in directly detected proton dimension of 13C-HSQC-NO
Baseline issues in directly detected proton dimension of 13C-HSQC-NO
Hello everyone, I have a pair of 13C-HSQC-NOESY for two different proteins collected on a Varian instrument (gnoesyChsqcSE.c). Both have very severe rolling

NMR spectroscopy in biology and medicine is generally performed in aqueous solutions, thus in (1)H NMR spectroscopy, the dominant signal often stems from the partly suppressed solvent and can be many orders of...

Re: Rolling Baseline
Replacing forst points is done via "LP -before" ... for example, to replace points 1 to 8 with 12 LP coefficients: LP -before -pred 8 -ord 12 The flags "-b"

[NMR software blog] Can Zero-Filling Correct the Baseline?
Can Zero-Filling Correct the Baseline?
I want to show you a proton spectrum that has puzzled me during the last weeks. It contains something that's quite typical and something that I can't explain. I have processed the spectrum in two different ways, with zero-filling and without it. The spectrum without zero-filling is black, the spectrum with zero-filling is green (the number of points is doubled).
