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 (v0.3.0)

Option 1: Install from PyPI (Recommended)

The easiest way to install SNID SAGE is directly from PyPI:

pip install snid-sage

Option 2: Virtual Environment (Recommended for Development)

We recommend using a virtual environment to avoid conflicts with other Python packages. This ensures a clean, isolated installation.

Using venv (Python's built-in virtual environment)

# Create virtual environment
python -m venv snid_env

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

# Install SNID SAGE
pip install snid-sage
 

Using conda

# Create conda environment
conda create -n snid_sage python=3.10
conda activate snid_sage

# Install SNID SAGE
pip install snid-sage
 

Option 3: Development Installation

For development or testing the latest features:

# Install from Test PyPI (development versions)
pip install -i https://test.pypi.org/simple/ snid-sage

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

Note: If you choose global installation, we recommend using pip install --user to install in your user directory rather than system-wide.

Getting Started

Launch the GUI (Recommended)

# Using installed entry point
snid-gui
# or
snid-sage

Use the CLI (For automation)

# Single spectrum analysis (templates auto-discovered). By default saves summary (.output) and plots
snid data/sn2003jo.dat -o results/

# Single spectrum with explicit templates
snid identify data/sn2003jo.dat templates/ -o results/

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

# Minimal outputs (summary only, no plots)
snid identify data/sn2003jo.dat -o results/ --minimal

# Complete outputs (summary, plots, and all additional data files)
snid identify data/sn2003jo.dat -o results/ --complete

# Disable plots explicitly (default is to generate plots)
snid identify data/sn2003jo.dat -o results/ --no-plots
