Dear Pipe users, I have the same problem as Kate: heavy baseline distortions in the acquisition dimension in the methyl region of some of my 2D and 3D noesys.
[Question from NMRWiki Q&A forum] qfil: baseline correction
qfil: baseline correction
"the t1 dimensio was processed using the baseline correction mode “qfil” in theXWINNMR software"
Does anyone know about "qfil" method in XWINNMR?How can I realize the "qfil" in vnmrJ?
Thanks in advance!

Hi Justin, This sensitivity enhanced experiment usually achieves good water suppression, but you could try removing some of the water with a polynomial solvent

Sequence correction of random coil chemical shifts: correlation between neighbor correction factors and changes in the Ramachandran distribution
Sequence correction of random coil chemical shifts: correlation between neighbor correction factors and changes in the Ramachandran distribution
Abstract Random coil chemical shifts are necessary for secondary chemical shift analysis, which is the main NMR method for identification of secondary structure in proteins. One of the largest challenges in the determination of random coil chemical shifts is accounting for the effect of neighboring residues. The contributions from the neighboring residues are typically removed by using neighbor correction factors determined based on each...

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...

The ETS family of transcription factors consists of a group of proteins that share a highly conserved 85 amino acid DNA-binding domain (DBD). This family recognizes a consensus sequence rich in purine bases with a central GGAA motif. A comparison of the published three-dimensional structures of...

[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).
