We provide the standard and fast modes of Spatom for users, which are described in our paper. The standard mode with better performance needs users to submit additional PSSM files. While the fast mode only needs users to provide a PDB file or a PDB ID and still shows excellent performance.

The number and the name of pssm files need to match the number of chains in the protein you input. For example, if you input a protein with Chain A and Chain B, you need to upload two pssm files named {pdbID}_A.pssm and {pdbID}_B.pssm.
