Pylians stands for Python libraries for the analysis of numerical simulations. They are a set of python libraries, written in python, cython and C, whose purposes is to facilitate the analysis of numerical simulations (both N-body and hydro). Among other things, they can be used to:
- Compute density fields
- Compute power spectra
- Compute bispectra
- Compute correlation functions
- Identify voids
- Populate halos with galaxies using an HOD
- Apply HI+H2 corrections to the output of hydrodynamic simulations
- Make 21cm maps
- Compute DLAs column density distribution functions
- Plot density fields and make movies
Pylians were the native or inhabitant of the Homeric town of Pylos.
Notice that Pylians only works with python2. For a python3 version see Pylians3.
From 2020 only Pylians3 will be supported/updated.
- numpy
- scipy
- h5py
- pyfftw
- mpi4py
- cython
- openmp
We recommend installing the first packages with anaconda.
cd library
python setup.py buildThe compiled libraries and scripts are in build/lib.XXX, where XXX depends on your machine. E.g. build/lib.linux-x86_64-2.7 or build/lib.macosx-10.7-x86_64-2.7
Add that folder to your PYTHONPATH in ~/.bashrc
export PYTHONPATH=$PYTHONPATH:$HOME/Pylians/library/build/lib.linux-x86_64-2.7The most updated documentation with examples can be found here.
