ctapipe Test Status Code Quality coverage conda doiv07

Low-level data processing pipeline software for CTA (the Cherenkov Telescope Array)

This is code is a prototype data processing framework and is under rapid development. It is not recommended for production use unless you are an expert or developer!

Citing this software

If you use this software for a publication, please cite using the following DOIs:

  • v0.7.0 : doiv07

Installation for Users

ctapipe and its dependencies may be installed using the Anaconda or Miniconda package system. We recommend creating a conda virtual environment first, to isolate the installed version and dependencies from your master environment (this is optional).

The following command will set up a conda virtual environment, add the necessary package channels, and download ctapipe and its dependencies. The file environment.yml can be found in this repo. Note this is pre-alpha software and is not yet stable enough for end-users (expect large API changes until the first stable 1.0 release).

conda env create -n cta -f environment.yml
conda activate cta
conda install -c cta-observatory ctapipe

Developers should follow the development install instructions found in the documentation.

You can’t perform that action at this time.
