SNID SAGE - SuperNova IDentification with Spectrum Analysis and Guided Enhancement

SNID SAGE - Advanced Supernova Spectral Analysis

SNID SAGE (SuperNova IDentification – Spectral Analysis and Guided Exploration) is your go-to tool for analyzing supernova spectra. It combines an intuitive PySide6/Qt graphical interface with the original SNID (Blondin & Tonry 2007) cross-correlation techniques, enhanced with modern clustering for classification choice, high-performance plotting via pyqtgraph, and LLM-powered analysis summaries and interactive chat assistance.

Quick Installation

Install from PyPI (Recommended)

pip install snid-sage

This installs both the CLI and the full GUI stack by default, as defined in pyproject.toml.

Using a virtual environment (recommended)

# Create virtual environment
python -m venv snid_env

# Activate environment
# Windows:
snid_env\Scripts\activate
# macOS/Linux:
source snid_env/bin/activate

# Install
pip install snid-sage

Development installation

git clone https://github.com/FiorenSt/SNID-SAGE.git
cd SNID-SAGE
pip install -e .

Note: For user installs, you can use pip install --user to avoid system-wide changes.

Getting Started

Launch the GUI

snid-sage

Use the CLI

# Single spectrum analysis (templates auto-discovered). Saves summary (.output) and plots by default
sage data/sn2003jo.dat -o results/

# Batch processing (default saves per-object summary and plots)
sage batch "data/*.dat" -o results/
