Description

This dataset is a subset of the public datasets from Salek et al. (2007). The experiment has been designed to improve the understanding of early stage of type 2 diabetes mellitus (T2DM) development. $^1$H-NMR human metabolome was obtained from 25 healthy volunteers and 25 T2DM patients. Raw 1D Bruker spectra were obtained from the MetaboLights database (https://www.ebi.ac.uk/metabolights/, study MTBLS1).
The dataset contains 50 spectra (columns in TXT file) and 31087 chemical shifts (rows in TXT file). Row names in the TXT file indicate the chemical shifts in ppm.

Format
