Abstract
Introduction
Metabolomics is the approach of choice to guide the understanding of biological systems and its molecular intricacies, but compound identification is yet a bottleneck to be overcome.
Objective
To assay the use of NMRfilter for confidence compound identification based on chemical shift predictions for different datasets.
Results
We found comparable results using the lead tool COLMAR and NMRfilter. Then, we successfully assayed the use of HMBC to add confidence to the identified compounds.
Conclusions
NMRfilter is currently under development to become a stand-alone interactive software for high-confidence NMR compound identification and this communication gathers part of its application capabilities.
Data availability
The sample data used are available in the github repository at https://github.com/stefhk3/nmrfilterprojects.
