Build/ Install

ExoSpec runs with Python 2.7.

Pre-Requisites

Before installing ExoSpec, you must install the following packages:

-Eigen3-

On linux:

$ sudo apt-get install libeigen3-dev

On mac:

$ brew install eigen

On Windows: the developers of george say they did not test george on Windows, so it may not work but you can still try. We have not tested ExoSpec on Windows

-OpenMPI-

On linux:

$ sudo apt-get install openmpi-bin openmpi-common openssh-client openssh-server libopenmpi1.3 libopenmpi-dbg libopenmpi-dev

On mac:

$ brew install openmpi

Installation

To install ExoSpec run

$ python setup.py install

Batman issues: If after running the setup.py file you receive and error from batman, you can install it from the source file instead. Download the stable release at https://pypi.python.org/pypi/batman-package/, and then run

$ sudo python setup.py install

in the batman directory.

Tests

To test that the code built correctly, cd to the tests folder and run the tests.py file:

$ cd exospec/tests
$ python tests.py

Usage

To run exospec on the two example files included, go into bin/ and simply run:

$ python exospec_main.py short_example.ini
$ python exospec_main.py full_example.ini

Please see the user manual in the docs/ folder for more detailed instructions on using exospec with other data.

Known Issues (v0.1)

Running
```
$ python setup.py tests
```
does not run the test suite. This needs to be further investigated.
Running tests.py with Jenkins on adroit throws an MPI error. We are currently working with David Luet to resolve this.
We need to add further tests to catch user input errors, such as typing nthreads = 4m instead of nthreads = 4. Currently we have the most basic tests set up.
