Method & evidence
Score residues in a protein structure, locate contiguous positive-score regions, and review surface accessibility alongside aggregation propensity.
Scope & limitations
- This method performs static Aggrescan3D scoring with FreeSASA accessibility.
- It does not run conformational-ensemble or FoldX mutation analysis.
Interpreting results
- Positive A3D scores identify aggregation-prone residues; negative values indicate aggregation-resistant local environments.
- The surface component reflects solvent exposure, while the neighborhood component reflects nearby aggregation-prone residues in 3D.
- Prioritize contiguous positive regions and inspect their structural context instead of relying on the total score alone.

Input requirements & outputs
Input checks
- PDB structure with standard protein residues
- Optional single-chain selection
- Up to 4 structures and 8 MB total input per analysis
Expected results
- Residue propensity map — Scan aggregation scores in structure order with positive hotspots highlighted.
- Contiguous positive regions — Prioritize stretches of positive-scoring surface residues.
- Chain-level summary — Compare minimum, maximum, mean, and total scores across chains.
