Install EMAN2/SPARX

It is best to install EMAN2/SPARX from source, so that do not have conflicts with having two different versions of python on your system. Binaries of EMAN2/SPARX all come with their own python pre-installed.

This documentation assumes you are using CentOS 6 (written as of CentOS 6.2)

Install require pre-packages for EMAN2 compiling

yum based packages

  • Make sure EPEL is install, if not go here: Download additional Software (CentOS Specific)
  • Use yum to install devel libraries:
    sudo yum install fftw-devel gsl-devel boost-python numpy \
     PyQt4-devel cmake ipython hdf5-devel libtiff-devel libpng-devel \
     PyOpenGL ftgl-devel db4-devel python-argparse openmpi-devel
    

bsddb3

Additionally you need to install the python-bsddb3 library (not available via YUM). I just use the pypi easy_installer, yum will never know.

sudo easy_install bsddb3

Download the source

  1. To download the source code go to the link:
  2. Click on "Current stable version - direct link"
  3. Go under the heading "Source" at bottom of page
  4. Click to download the eman-source-2.xx.tar.gz file (as of August 2012, 2.xx is 2.06)

Work with the source

  1. go to the directory with the source code
  2. extract the archive:
    tar zxvf eman-source-2.06.tar.gz
    
  3. go into directory
    cd EMAN2/src/build
  4. start configure script:
    cmake ../eman2/
    • Note: alternatively you can run ccmake ../eman2/ and configure all the parameters
  5. start compiling:
    make
  6. install to directory:
    sudo make install

Set environmental variables

bash

sudo nano /etc/profile.d/eman2.sh
export EMAN2DIR=/usr/local/EMAN2
export PATH=${EMAN2DIR}/bin:${PATH}
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${EMAN2DIR}/lib
export PYTHONPATH=${EMAN2DIR}/lib:${EMAN2DIR}/bin

c shell

sudo nano /etc/profile.d/eman2.csh
setenv EMAN2DIR /usr/local/EMAN2
setenv PATH ${EMAN2DIR}/bin:${PATH}
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${EMAN2DIR}/lib
setenv PYTHONPATH ${EMAN2DIR}/lib:${EMAN2DIR}/bin

Install MyMPI

  • Download source:
    wget -O pydusa-1.15-sparx.tgz \
     'http://sparx-em.org/sparxwiki/MPI-installation?action=AttachFile&do=get&target=pydusa-1.15-sparx.tgz'
  • Extract:
    tar zxvf pydusa-1.15-sparx.tgz
  • go into directory
    cd pydusa-1.15-sparx

    nano configure

    elif test -d ${PY_PREFIX}/lib/python$PY_VERSION/site-packages/numpy/core/include; then
       PY_HEADER_NUMPY="-I${PY_PREFIX}/lib/python$PY_VERSION/site-packages/numpy/core/include" 
    
    elif test -d ${PY_PREFIX}/lib64/python$PY_VERSION/site-packages/numpy/core/include; then
       PY_HEADER_NUMPY="-I${PY_PREFIX}/lib64/python$PY_VERSION/site-packages/numpy/core/include" 
    
  • Configure:
    setenv MPIROOT /usr/lib64/openmpi
    setenv MPIINC /usr/include/openmpi-x86_64
    setenv MPILIB ${MPIROOT}/lib
    setenv MPIBIN ${MPIROOT}/bin
    ./configure
    

    export MPIROOT=/usr/lib64/openmpi
    export MPIINC=/usr/include/openmpi-x86_64
    export MPILIB=${MPIROOT}/lib
    export MPIBIN=${MPIROOT}/bin
    ./configure
    
  • compile the source:
    make
  • copy the mpi.so to site-packages with a different name:
    sudo mkdir /usr/lib64/python2.6/site-packages/mympi/
    sudo touch /usr/lib64/python2.6/site-packages/mympi/__init__.py
    sudo cp -v src/mpi.so /usr/lib64/python2.6/site-packages/mympi/mpi.so
    
  • create a wrapper around the wrapper:
    sudo nano /usr/lib64/python2.6/site-packages/mpi.py

    import ctypes
    mpi = ctypes.CDLL('libmpi.so.1', ctypes.RTLD_GLOBAL)
    from mympi.mpi import *
    

    This needs to be done to avoid the error:
    python: symbol lookup error: 
      /usr/lib64/openmpi/lib/openmpi/mca_paffinity_hwloc.so: 
        undefined symbol: mca_base_param_reg_int
    
  • test 1:
    python -c 'import mpi'
    python -c 'import sys; from mpi import mpi_init; mpi_init(len(sys.argv), sys.argv)'
    
  • test 2:
    sxisac.py start.hdf

    (Note: start.hdf does not need to exist, if it does not exist then it should exit with file not found)

Test to see if code works

see http://blake.bcm.edu/emanwiki/EMAN2/FAQ/EMAN2_unittest

cd EMAN2/test/rt
./rt.py

Install MyMPI for MPI functions

see http://sparx-em.org/sparxwiki/MPI-installation
or https://www.nbcr.net/pub/wiki/index.php?title=MyMPI_Setup

This fixes this problem:

    from mpi import mpi_init
ImportError: No module named mpi

This module was very difficult to get working, it seems to be a poorly supported python wrapper for MPI. So, what we are going to do is compile the module, rename it, and create a wrapper. So, essentially we are creating a wrapper around the wrapper. We can only hope they switch to [http://mpi4py.scipy.org/ mpi4py] in the future.
