The LPH based barcodes for different combinations of DNA base pairs. It can be seen that A-T and G-C base pairs all have three local \({\beta }_{1}\) bars from around 1.4 Å to 2.4 Å. But they differ greatly in the global region, where A-T pair contributes one significant \({\beta }_{1}\) bar from around 2.9 Å to 3.6 Å, while G-C pair generates two. These barcode fingerprints characterize the intrinsic DNA structure properties, i.e., local and global loop/ring motifs.
