a The three-dimensional view of \(GC\times GC\) image of crude oil sample from Eugene Island, Gulf of Mexico, about 50 miles southwest of MW, the oil source of the Deepwater Horizon disaster. b The two-dimensional view of the full chromatogram, with yellow box showing region of interest (hopanes and steranes) detailed in a. c Two-dimensional view of detailed topography of biomarker region (hopanes and steranes) marked as yellow box in b.Target biomarkers are labeled and itemized in Table S2. d PTM representation of ROI shown as yellow box in b. Thirty-eight target biomarkers are allocated to the numerically labeled PTM nodes. Each PTM node is uniquely assigned to each peak and therefore, each target peak is uniquely identifiable against the non-target peaks
