hello, I am trying to identify and quantify of metabolites present in semen with spectra obtained from 400 MHz NMR using chenomx software. I have fit about 43 metabolites. I am sure that we must have ATP in our samples but it can not be fit and clusters in 6.1, 8.3 and 8.5 have been missed. So I am not sure about my results and I don't know what has happened. thank you for your answer.

Integrating peaks in 2D NMR
Hi,
I want to integrate only say x% of peak height of a given peak. We don't want to go to base level and let noise or neighbouring peak interfere with our peak volume. Can anyone help me if this can be done in some software like Topspin/Xeasy etc
Thanks

[Question from NMRWiki Q&A forum] Chenomx Libraries
Chenomx Libraries
Hey all--
I've been using Chenomx Suite for metabolomics research. Chenomx allows the user to create custom compounds from their own experimental spectra, so that the user is not limited to those compounds which come with the software. My questions are these:
If my laboratory comes up with a library of "custom" compounds to fit our needs, is there any legal reason why we would not be allowed to make that library public, so that others could also benefit? I'm only asking because the file type, .cnx, is proprietary.
If there is no reason, are there any...

[Question from NMRWiki Q&A forum] peak missing in nh hsqc protein nmr
peak missing in nh hsqc protein nmr
Dear NMR wikiers
iam assigning 95 aminoacid residue protein . i can see 76 cross peaks in hsqc on 700 vnmr cryob . still some peaks are missing . i tried at modified ph conditions , buffer ionic strength and d2o percentage ( 5 to 10 percent ).but no significant improvement
is their any experment to get best number of cross peaks in hsqc ?

[Question from NMRWiki Q&A forum] negative NMR peaks
negative NMR peaks
I am very new to NMR and have little experience of it. However I am trying to use it to determine the composition of a mixture. A spectra which I have just obtained contains negative peaks which are giving me incorrect inegrals.
What would cause this? and is there any way to correct it? I can't find much in literature regarding this.
Thanks for your help
