| <li><strong>Drug input supports both SELFIES and SMILES:</strong><br> | |
| You can enter a SELFIES string directly, or paste a SMILES string. | |
| SMILES will be automatically converted to SELFIES using | |
| <a href="https://github.com/aspuru-guzik-group/selfies" target="_blank">SELFIES encoder</a>. | |
| If conversion fails, a red error message will be displayed.</li> | |
| <li>Optionally enter a <strong>1-based</strong> drug atom or substructure index | |
