Installation

Install the dependencies required to carry out the data simulation and EoR signal separation.

1. Dependencies directly installed from the repository (Debian Linux; testing; amd64):

   $ sudo apt install \
         bison \
         cmake \
         flex \
         g++ \
         gfortran \
         libboost-all-dev \
         libcfitsio-dev \
         libfftw3-dev \
         libgsl-dev \
         libhdf5-dev \
         libopenblas-dev \
         wcslib-dev \
         zlib1g-dev \
         python-dev \
         python-numpy \
         qtbase5-dev

   On openSuSE (maybe also CentOS), use:

   $ sudo zypper install \
         bison \
         cmake \
         flex \
         gcc \
         gcc-c++ \
         gcc-fortran \
         boost-devel \
         cfitsio-devel \
         fftw3-devel \
         fftw3-threads-devel \
         gsl-devel \
         hdf5-devel \
         blas-devel \
         lapack-devel \
         wcslib-devel \
         zlib-devel \
         ...

2. Install CUDA:

   $ sudo apt install nvidia-cuda-toolkit

3. Install CASA Core

   $ git clone https://github.com/casacore/casacore
   $ cd casacore
   # Checkout the v2.4.1, which has been tested with OSKAR.
   # (the latest master as of 2018-10-30 causes error in building OSKAR)
   $ git checkout v2.4.1
   $ mkdir build && cd build
   $ cmake .. \
         -DCMAKE_INSTALL_PREFIX=$HOME/local/casacore \
         -DUSE_OPENMP=ON \
         -DUSE_THREADS=ON \
         -DUSE_FFTW3=ON \
         -DUSE_HDF5=ON
   $ make
   $ make install

4. Install OSKAR

   $ git clone https://github.com/OxfordSKA/OSKAR oskar
   $ cd oskar
   $ git checkout 2.7.0
   $ mkdir build && cd build
   $ cmake .. \
         -DCMAKE_INSTALL_PREFIX=$HOME/local/oskar \
         -DCMAKE_INSTALL_RPATH='$ORIGIN/../lib' \
         -DCASACORE_LIB_DIR=$HOME/local/casacore/lib \
         -DCASACORE_INC_DIR=$HOME/local/casacore/include \
         -DFIND_CUDA=ON
   $ make
   $ make install
   $ cd ~/bin && ln -s ../local/oskar/bin/oskar_sim_interferometer .

5. Install WSClean

   $ git clone https://git.code.sf.net/p/wsclean/code wsclean-code
   $ cd wsclean-code/wsclean
   $ git checkout wsclean2.6
   $ mkdir build && cd build
   $ cmake .. \
         -DCMAKE_INSTALL_PREFIX=$HOME/local/wsclean \
         -DCMAKE_PREFIX_PATH=$HOME/local/casacore
   $ make
   $ make install
   $ cd ~/bin && ln -s ../local/wsclean/bin/wsclean .

6. Clone this repo and create the Python virtualenv:

   $ git clone https://github.com/liweitianux/cdae-eor
   $ cd cdae-eor
   $ make venv
   $ source venv/bin/activate
   (venv)$ # ready to go :-)
