Spinworks and MatNMR Inconsistencies
Hello,
I'm pretty new to NMR, and am just trying to do some simple data processing with a 1D ethanol spectrum I got from a Bruker spectrometer. I opened it in Spinworks and it appears to be normal, when I take the Fourier transform the spectrum is what I expected. I wanted to process this in Matlab however, so I used MatNMR to load the FID into Matlab. It seems though, that a lot of the data is for negative time values. When I take the Fourier transform it looks quite different and is considerably more noisy.
Given that the data is the same, is there something that spinworks does...

[Question from NMRWiki Q&A forum] Processing 1D FID of ethanol exported from spinworks
Processing 1D FID of ethanol exported from spinworks
Hello,
This is probably a basic question, alas it has caused considerable turmoil, so at the risk of embarrassing myself. . . I am trying to implement some algorithms for processing NMR spectra using Matlab.
I got data for the 1D FID of ethanol from the biomolecular magnetic resonance database which, as far as I can tell, is in the Bruker format. I opened the file in spinworks without problems and used the "export xy data" function to get a text file of what appears to be the real channel(?)
I loaded this into Matlab and the...
