Diagnostic Data for Sampling Issues in Protein-Ligand Binding Free Energy Simulations

An automated workflow for diagnosing sampling issues in molecular simulations, developed by Meghan Osato and published on figshare in May 2026. The 103.4 MB dataset likely contains analysis results from postsimulation diagnostics of torsional motions in protein and ligand structures. It focuses on identifying slow conformational changes that can impact the accuracy of binding free energy estimates.

Use Cases

• Validating the convergence of molecular dynamics simulations based on dihedral angle state transitions mentioned in the description.
• Benchmarking automated diagnostic tools for slow torsional rotations in protein-ligand systems.
• Improving the reliability of binding free energy calculations by identifying insufficiently sampled conformational degrees of freedom.
• Training machine learning models to predict simulation convergence issues from torsion analysis data.

Strengths

• Dataset size is 103.4 MB, indicating a medium-scale analysis output.
• Method is specifically designed for postsimulation analysis of a defined problem (slow torsional rotations).
• License is clearly defined as CC-BY-NC-4.0.

Limitations

• Row count and specific column definitions are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect methodological bias inherent to the specific simulation and analysis workflow described.
