Data Export Guide
Export Options
The Materials Database allows you to export data in several formats:
- CSV Format: For spreadsheet applications (Excel, Google Sheets)
- JSON Format: For programmatic access and analysis
- CIF Files: For structure analysis in crystallographic software
- Custom Formats: For specialized simulation packages
Exporting Individual Materials
From the Material Detail Page
To export data for a single material:
- Navigate to the material's detail page
- Click the "Export" button in the top right corner
- Select the desired export format
- Choose which properties to include
- Click "Download" to save the file
Export Content Options
You can customize what data to include:
- Basic Properties: Name, ID, status
- Structure Data: Unit cell, atomic positions
- Electronic Properties: Band gap, Fermi level, workfunction
- Energetics: Formation energy, total energy
- Files: Include associated files (CIF, band data, etc.)
Batch Exporting Multiple Materials
From the Search Results
To export data for multiple materials:
- Perform a search to find materials of interest
- Select materials using the checkboxes (or "Select All")
- Click the "Export Selected" button
- Choose the export format and options
- Click "Download" to save the file
From Collections
If you've created material collections:
- Navigate to the "Collections" page
- Open the collection containing your materials
- Click "Export Collection"
- Select format and options
- Download the file
API Access
For programmatic access to the database:
- Request an API key from your administrator
- Use HTTP requests to fetch data:
GET /api/v1/materials?property=bandgap&value=>2.0
- Responses will be in JSON format by default
- For large datasets, use pagination parameters:
GET /api/v1/materials?limit=100&offset=200
Best Practices
- Selective Export: Only export the properties you need to keep file sizes manageable
- Batch Processing: For very large exports, consider using the API with scripts
- Data Citation: Remember to cite the database when using exported data in publications
- Versioning: Note the database version/date when exporting for reproducibility
