Overview
SOPRANO (Simulated Phonon Raman and NMR Observables) is a Python library for crystal structure generation, manipulation, and analysis. It provides tools for handling collections of structures and computing various properties.
Theoretical Basis
- Crystal structure manipulation
- Symmetry analysis
- Structure comparison (SOAP, etc.)
- NMR parameter prediction
- Phonon-related properties
Key Capabilities
- Structure collection handling
- Symmetry operations
- Structure comparison metrics
- NMR chemical shift prediction
- Integration with CASTEP/Magres
Sources: SOPRANO documentation, CCP-NC
Key Strengths
Structure Handling:
- Collection management
