Real Glycoproteomics Experiment

real_experiment.Rd

A real glycoproteomics experiment object. This dataset is derived from the unpublished ProteomeXchange dataset PXD063749. It contains serum N-glycoproteome profiles from 12 patients with different liver conditions: healthy (H), hepatitis (M), cirrhosis (Y), and hepatocellular carcinoma (C). Glycopeptide identification and annotation were performed using pGlyco3 (https://github.com/pFindStudio/pGlyco3), and quantification was carried out with pGlycoQuant (https://github.com/Power-Quant/pGlycoQuant). The raw data were imported with glyread::read_pglyco3_pglycoquant().

Usage
