Structure 2 Sequence Report

Structure-to-Sequence (s2s) is a computing process based on RDkit and the characteristics of cyclic peptide sequences, which can convert cyclic peptide SMILES into sequence information. This process mainly relies on the completeness of the monomer reference library. You can access our default monomer reference library through download link. The details of s2s are available on dfwlab/cyclicpepedia on Github. And you can use this tool online on the cyclicpepedia.
