Welcome to Clavis

Clavis is a web-based tool for analyzing and visualizing gas hydrate cage structures. Built for researchers studying clathrate hydrates, Clavis provides real-time 3D visualization and automated cage detection.

​
What is Clavis?

Clavis (Latin for “key”) helps you unlock the structural secrets of gas hydrates by:
  • Detecting cage structures using TRACE and HTR algorithms
  • Visualizing H-bond networks with interactive 3D rendering
  • Calculating order parameters (F3/F4) for structure characterization
  • Analyzing trajectories with multi-frame support
  • Creating publication-quality renders with GPU path tracing PRO

​
Supported File Formats

Currently supported:
  • .gro (GROMACS format)

​
Quick Start

  1. Upload your .gro file
  2. Select an analysis algorithm (TRACE, HTR, or GRADE)
  3. Run the analysis
  4. Explore the detected cages in 3D
