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!

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...	nmrlearner	Journal club	0	06-06-2011 12:53 AM

[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). http://2.bp.blogspot.com/_ROkYShLRKqA/TGu61b5bG7I/AAAAAAAAAUQ/9AbsXlWbKUY/s400/TMS.pngThis detail is the bottom part of the TMS signal (magnified to show the ringing effect).
