DOSY NMR Spectroscopy of Human Plasma Lipoproteins

2D diffusion-edited proton NMR spectra and lipoprotein reference measurements for human plasma samples, used for multi-way calibration by N-PLS and multi-way curve resolution by PARAFAC. The MATLAB file webnmr.mat contains Dataset Object variables X and Y plus index vectors ch2 and ch3. X.data has shape 25 x 24 x 1600 for sample x squared-gradient level x chemical-shift variable; Y.data has shape 25 x 32 and contains cholesterol-related and triglyceride-related lipoprotein measurements for main fractions and subfractions. The source publication reports written informed consent from the volunteers; the shared file contains numeric sample labels, spectra, lipoprotein measurements, and axis/metadata fields, with no direct personal identifiers.
