iMolTalk works on macromolecular structures in PDB formatted files. It knows about PDB released structures but you may use your own files too.

You may choose from different approaches:

If you already know a structure's PDB (4-letter) identifier enter it in the first field and press "Next" to continue.

To analyse an uploaded model, you may enter its code.

Alternatively, ModBase entries may be directly accessed through their identification by the Swiss-Prot/Trembl accession code (AC).
