Structure Prediction and Omics informed Classifier (SPOC) Tool

This tool calculates compact SPOC (cSPOC; Schmid and Walter) scores and other confidence metrics (pDOCKQ, ipTM, avg_models) for user-uploaded AlphaFold multimer (AF-M) predictions. Results are confidential*.

The tool will only process binary predictions of human proteins. For the SPOC score to be valid, predictions should involve structures generated with AF-M default settings (1 ensemble, 3 recycles) to match the training regimen for SPOC.

Drag and drop data files for one or more protein pairs (up to 50) below. For every pair to be analyzed, please supply a total of 6 AF-M output files:

3 ".PDB" structure files
e.g. PROTEIN1-PROTEIN2_unrelaxed_rank_001_alphafold2_multimer_v3_model_4_seed_000.pdb
3 ".JSON" Predicted Angstrom Error (pAE) files
e.g. PROTEIN1-PROTEIN2_scores_rank_001_alphafold2_multimer_v3_model_4_seed_000.json

If more than 3 models per complex are uploaded, the tool randomly analyzes 3 models to mirror the classifier's training regimen.

*We track the number of structures submitted per user, but not which structures were submitted, and structures and results are immediately deleted after analysis.
