sample_qc_info

Contains details on the sample processing and quality control information for
the NMR biomarker data in UK Biobank.

datasets

A suite of utilities for working with the UK Biobank
<https://www.ukbiobank.ac.uk/> Nuclear Magnetic Resonance spectroscopy (NMR)
metabolomics data <https://biobank.ndph.ox.ac.uk/showcase/label.cgi?id=220>.
Includes functions for extracting biomarkers from decoded UK Biobank field
data, removing unwanted technical variation from biomarker concentrations,
computing an extended set of lipid, fatty acid, and cholesterol fractions,
and for re-deriving composite biomarkers and ratios after adjusting data
for unwanted biological variation. For further details on methods see
Ritchie SC et al. Sci Data (2023) <doi:10.1038/s41597-023-01949-y>.
