The files are comma separated and contain measurements for 46 N-glycan peaks on 1581 serum samples (corresponding to 1565 unique participants) from SDRNT1BIO and from a pool of healthy controls. N-glycan peaks are expressed as absolute levels in ng/µL in volume of serum and as percentage areas (in this case, result files also contain a Man3 column).
File 'sample_script.R' contains code to read these files, recompute percentage areas after exclusion of Man3, and derivation of 18 summary measures that aggregate the sums of peaks having features related to antennary structure, galactosylation, fucosylation, or sialylation.
