GEMC Analyzer is available

GEMC now includes analyzer, a small Python package for reading GEMC output files and plotting variables by name.

The first implementation focuses on CSV and ROOT output from gstreamer. It can read digitized and true information tables, flatten ROOT detector trees into pandas data frames, and make quick histograms from either Python, Jupyter, or the command line.

What it does

• Reads GEMC CSV output such as b2_t0_digitized.csv and b2_t0_true_info.csv
• Reads GEMC ROOT output such as b2_t0.root
• Returns data as DataFrame objects for inspection and analysis
• Plots variables by name, for example totEdep
• Supports detector selection for ROOT detector trees
• Provides a dependency-free SVG histogram helper for minimal systems

See the Analyzer documentation for dependencies, Python examples, command-line examples, Jupyter usage, CSV and ROOT output details, and B2 example commands.
