p2smi: A Python Toolkit for Peptide FASTA-to-SMILES Conversion and Molecular Property Analysis
p2smi is a Python toolkit that converts peptide sequences from FASTA format into SMILES strings. It specifically handles complex structures like noncanonical amino acids and various cyclization chemistries. This tool was created to generate large datasets of peptide SMILES for training machine learning models, bridging the gap between biological sequences and chemical notation.
