Python extension of NRAO's VLBI scheduling program SCHED (see http://www.aoc.nrao.edu/~cwalker/sched/)
Project description
pySCHED
pySCHED is built upon SCHED as developed by Craig Walker at NRAO.
Installation
pip
sudo pip3 install numpy
sudo pip3 install pythonSCHED
The setup script of pySCHED requires NumPy (>=1.16).
pip3 is included in most python3 installations, otherwise it can be installed with:
sudo apt-get install python3-pip
conda
Alternatively, if you use conda, this YAML file is a conda environment which includes both NumPy and pySCHED. To use it
conda env create -f pySCHED.yaml
conda activate pySCHED
Update
The command to update pySCHED is:
sudo pip3 install --upgrade pythonSCHED
Or when using a conda installation:
conda activate pySCHED
pip install --upgrade pythonSCHED
Usage
After executing either the pip or conda installation method, the executable sched.py should be available in your $PATH.
One of the features of pySCHED is that the catalog files will be downloaded/updated on start-up of sched.py. This allows for the catalog files to be updated separate from the pySCHED release cycle. The files will be installed in ~/.pysched. $SCHED will be set to this directory in pySCHED if not otherwise specified. The process of downloading and updating requires the version control software git to be installed and available in the $PATH. On most Linux systems, git will be available. If it is not, it can be installed with:
sudo apt-get install git
