A fast radio interferometric transient search library. Extends on rtpipe.

This library primarily supports offline analysis of VLA data on a single workstation. Integration with the real-time VLA and cluster processing is provided by realfast.

Planned future development include:

  • Supporting other search algorithms.
  • Extending support for GPUs.
  • Supporting other interferometers by adding data and metadata reading functions.
  • Remove dependence on rtpipe.
  • Python 3 support.

rfpipe requires the anaconda installer on Linux and OSX. The most reliable install process adds two custom channels and a new build environment.

conda config --add channels pkgw-forge
conda config --add channels conda-forge
conda create -n realfast numpy scipy cython matplotlib pwkit casa-tools casa-python casa-data numba pyfftw
source activate realfast
pip install -e git+git://


  • numpy/scipy/matplotlib
  • pwkit casa environment (for quanta and measures)
  • numba (for multi-core and gpu acceleration)
  • rtpipe (for flagging; will be removed soon)
  • astropy (<3.0; for Python2 and 3 compatibility)
  • sdmpy
  • pyfftw
  • pyyaml
  • attrs
  • rfgpu (optional; for GPU FFTs)
  • vys/vysmaw and vysmaw_reader (optional; to read vys data from VLA correlator)
