Spectral Coherence Index: A Model-Free Metric for Protein Structural Ensemble Quality Assessment

1. 1Compute the inter-model pairwise distance-variance matrix
2. 2Calculate the participation-ratio effective rank of the matrix
3. 3Derive the Spectral Coherence Index (SCI) as a rotation-invariant summary
4. 4Evaluate the SCI to assess the quality of protein structural ensembles

Researchers and scientists in the field of bioinformatics and structural biology can benefit from this metric to evaluate the quality of protein structural ensembles, while data scientists and AI engineers can apply this concept to other domains

💡 The Spectral Coherence Index provides a model-free and rotation-invariant metric for evaluating protein structural ensemble quality
