Install EMAN2/SPARX

Before you begin:
Please note that Appion 2.2, Appion 2.2-redux and any earlier releases do not include any features that require EMAN2/SPARX to be installed. Appion 3.0, the development trunk and future releases will require this software.
This documentation assumes you are using CentOS 6 (written as of CentOS 6.5)
It is best to install EMAN2/SPARX from source to get MPI working on a cluster or to avoid conflicts with having two different versions of python on your system. Binaries of EMAN2/SPARX all come with their own python pre-installed.

Install pre-requisite 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 boost148-python numpy libjpeg-devel \
 PyQt4-devel cmake ipython hdf5-devel libtiff-devel libpng-devel boost148-devel \
 PyOpenGL db4-devel python-argparse openmpi-devel python-pip freeglut-devel ftgl-devel

Download the source

  1. To download the source code go to the link:
  2. Click on "Main EMAN2 Download Page"
  3. Click on "Download EMAN 2", whichever is the latest release of EMAN.
  4. Scroll down to Source to download the eman2.1beta3.source.tar.gz

Work with the source

  1. go to the directory with the source code
  2. extract the archive:
    tar zxvf eman2.12.source.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
    • I had to disable ftgl (fonts in OpenGL) to get 2.12 to compile.
    • I had to manually set BOOST_LIBRARY=/usr/lib64/boost148/libboost_python.so
    • I had to manually set BOOST_INCLUDE_PATH=/usr/include/boost148
    • I had to manually set FREETYPE_INCLUDE_PATH=/usr/include/freetype2/
    • I had to manually set FTGL_INCLUDE_PATH=/usr/include/FTGL/
    • I had to manually set FTGL_LIBRARY=/usr/lib64/libftgl.so

  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

  • First, add the openmpi module so that MyMPI can find it.
    module add openmpi-i386
-or-
module add openmpi-x86_64
  • Download source:
    From the main software page: http://ncmi.bcm.tmc.edu/ncmi/software/software_details?selected_software=counter_222 scroll to MPI Support.
    Click on Download MPI Support
    Click on pydusa-1.15es.tgz
  • Extract:
    tar zxvf pydusa-1.15es.tgz
  • go into directory
    cd pydusa-1.15es

     
    If you are on a 64bit machine, you may have problems with the code finding the numpy headers:
     
    nano configure

     
    find the line:
    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"

    and replace it with:
     
    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

    Please ensure mpicc was found. If it is not found, a version of MPI will be installed that may cause errors. Look for the following error and correct this issue before moving on:
    configure: error: Unable to find mpicc! mpicc location can be specified with --with-mpicc

     
  • 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.
