1D NMR Metabolomics Baseline Correction Dataset for Biofluids and Tissue Extracts

To ensure the reliability of the data as a benchmark for downstream algorithms, all raw spectral data underwent meticulous manual phase and baseline corrections by experienced spectroscopists. This processing step removed the original baseline drift caused by instrument hardware factors, resulting in high-quality, pristine, baseline-free reference spectra. The dataset has been rigorously screened, with complete records and no missing data.

As the data have been expertly corrected manually, they represent recognized high-quality benchmarks in the field; the infinitesimal subjective interpretation residuals from experts do not compromise their validity as authentic references for algorithm training.The files in this dataset are stored in the standard data format of Bruker NMR instruments. Each data file fully retains the experimental acquisition parameters and spectral signal content.

This format offers excellent compatibility, allowing users to directly read, visualize, and process the spectra using the official Bruker TopSpin software (a free academic version is available for download on the official website) without the need for any additional data format conversion.
