Upload a PDB, ENT or Mol2 structure up to 30 MB and choose a calculation mode. Your results page includes the output files, available contact plots and a ZIP download.

Mode 0 — SASA

Solvent accessible surface areas.

Mode 1 — Intermolecular CSA

Buried surface areas between molecular objects, grouped automatically by molecular type.

Mode 2 — Residue contacts

Intramolecular buried surface areas between residues.

Mode 3 — Atom contacts

Intramolecular buried surface areas between atoms.

Mode 4 — Contact surface area

Contact surfaces between molecular objects without requiring solvent accessibility.

Some structures and modes do not produce contact plots. When plotting is unavailable, the original surface data remains downloadable. Calculations have a 20 minute limit, with up to 10 additional minutes for plots and packaging.

Keep your results link: anyone with the link can access the uploaded structure and results.
