Evaluation of models predicting the dihedral angles (torsion angles, chi1 through chi4) of side chains using the CrossDocked dataset.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Sidechain torsion angle prediction |
| Dataset (including any stated split) | CrossDocked |
| Metric | MAE (chi1) |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 2 of 2 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [MAE (chi1)](<https://www.sota2.com/research/sota/sidechain-torsion-angle-prediction-on-crossdocked.md?metric=MAE%20(chi1)>): Lower is better; unit: SCALAR.

- [MAE (chi2)](<https://www.sota2.com/research/sota/sidechain-torsion-angle-prediction-on-crossdocked.md?metric=MAE%20(chi2)>): Lower is better; unit: SCALAR.

- [MAE (chi3)](<https://www.sota2.com/research/sota/sidechain-torsion-angle-prediction-on-crossdocked.md?metric=MAE%20(chi3)>): Lower is better; unit: SCALAR.

- [MAE (chi4)](<https://www.sota2.com/research/sota/sidechain-torsion-angle-prediction-on-crossdocked.md?metric=MAE%20(chi4)>): Lower is better; unit: SCALAR.
