User Complex Interface
Analysis

Upload your own PDB complex file to analyze protein–protein interfaces, compute surface areas, and identify interface residues.

Submit your complex

Input guidelines

  • Upload a PDB file containing at least two protein chains.
  • Do not upload a monomer — this tool requires a complex.
  • Use a simple one-word filename with no spaces.
  • The server will compute interface residues, buried atoms, polar/apolar surface areas, and total surface area per chain.
  • Results open in a new tab upon submission.
