Installation

Prerequisites

Verif requires NetCDF as well as the python packages numpy, scipy, and matplotlib. The python package mpltoolkits.basemap is optional, but provides a background map when verification scores are plotted on a map. Install the packages as follows:

sudo apt-get update
sudo apt-get install netcdf-bin libnetcdf-dev libhdf5-serial-dev
sudo apt-get install python-setuptools python-pip
sudo apt-get install python-numpy python-scipy python-matplotlib python-mpltoolkits.basemap

Installing using pip

After this, the easiest is to install the lastest version of Verif using pip:

sudo pip install verif

Verif should then be accessible by typing verif on the command-line. If you do not have sudo-rights, then install verif as follows:

pip install verif --user

This will create the executable ~/.local/bin/verif. Add this to your PATH environment variable if necessary (i.e add export PATH=$PATH:~/.local/bin to ~/.bashrc).

Installing from source

Alternatively, to install from source, download the source code of the latest version: https://github.com/WFRT/verif/releases/. Unzip the file and navigate into the extracted folder.

Then install Verif by executing the following inside the extracted folder:

sudo pip install -r requirements.txt
sudo python setup.py install

This will create the executable /usr/local/bin/verif. Add /usr/local/bin to your PATH environment variable if necessary. If you do not have sudo privileges do:

pip install -r requirements.txt --user
python setup.py install --user

This will create the executable ~/.local/bin/verif. Add ~/.local/bin to your PATH environment variable.

Installing on Mac OSX

Follow the proceedure as for Ubuntu (either installing with pip or from source). If installing from source, then look for the line "Installing verif script to <some directory>", as this will indicate what folder Verif is installed into. Add the folder to your PATH environment variable if necessary.
