Each protein chain is represented using 6 lines:
1: Protein ID and type of binding
2: Amino acid sequence
3: Space-separated RAA values for each residus
4: Space-separated native RSA values for each residue (* means that the value could not be computed since structure of this residue was missing in the PDB file)
5: Space-separated putative RSA values for each residue
6: Space-separated ECO value for each residue
