An easy to use interface to gravitational wave surrogate models
Project description
Welcome to GWSurrogate!
-----------------------
GWSurrogate is an easy to use interface to gravitational wave surrogate models.
Surrogates provide a fast and accurate evaluation mechanism for gravitational
waveforms which would otherwise be found through solving differential
equations. These equations must be solved in the ``building" phase, which
was performed using other codes. For details see:
[1] Scott Field, Chad Galley, Jan Hesthaven, Jason Kaye, and Manuel Tiglio.
`"Fast prediction and evaluation of gravitational waveforms using surrogate
models". Phys. Rev. X 4, 031006 (2014). arXiv: gr-qc:1308.3565
If you find this package useful in your work, please cite reference [1] and,
if available, the relevant paper describing the specific surrogate used.
gwsurrogate is available at https://pypi-hypernode.com
Installation
------------
gwsurrogate is a pure-Python module, thus installation is very easy.
From pip:
The python package pip supports installing from PyPI (the Python Package
Index). gwsurrogate can be installed to the standard location
(e.g. /usr/local/lib/pythonX.X/dist-packages) with
>>> pip install gwsurrogate
From source:
Download and unpack gwsurrogate-X.X.tar.gz to any folder gws_folder of your
choosing. The gwsurrogate module can be used immediately by adding
import sys
sys.path.append('absolute_path_to_gws_folder')
at the beginning of any script/notebook which uses gwsurrogate.
Alternatively, if you are a bash or sh user, edit your .profile
(or .bash_profile) file and add the line
export PYTHONPATH=~absolute_path_to_gws_folder:$PYTHONPATH
For a "proper" installation into gws_folder run
>>> python setup.py install --prefix=absolute_path_to_gws_folder
and edit the PYTHONPATH environment variable as described above.
Getting Started
---------------
Please read the gwsurrogate docstring found in the __init__.py file
or from ipython with
>>> import gwsurrogate as gws
>>> gws?
Additional examples can be found in the accompanying ipython notebooks
located in the 'tutorial' folder. To open a notebook, for example
basics.ipynb, do
>>> ipython notebook example1.ipynb
from the directory 'notebooks'
Where to find surrogates?
-------------------------
Surrogates can be downloaded directly from gwsurrogate.
For download instructions see the basics.ipynb ipython notebook.
Tests
-----
If you have downloaded the entire project as a tar.gz file, from the
top folder, do
>>> py.test
NSF Support
