h1. 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.
h2. Install pre-requisite packages for EMAN2 compiling
h3. yum based packages
* Make sure EPEL is install, if not go here: [[Download additional Software (CentOS Specific)]]
* Use yum to install devel libraries:
<pre>
sudo yum install fftw-devel gsl-devel boost-python numpy libjpeg-devel \
PyQt4-devel cmake ipython hdf5-devel libtiff-devel libpng-devel \
PyOpenGL db4-devel python-argparse openmpi-devel python-pip freeglut-devel
</pre>
h3. Download and install FLGL
download
<pre>
wget 'http://downloads.sourceforge.net/project/ftgl/FTGL%20Source/2.1.3%7Erc5/ftgl-2.1.3-rc5.tar.gz?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fftgl%2Ffiles%2FFTGL%2520Source%2F&ts=1464027951&use_mirror=pilotfiber' -O ftgl-2.1.3-rc5.tar.gz
</pre>
unzip
<pre>
tar zxvf ftgl-2.1.3-rc5.tar.gz
</pre>
setup, compile, and install
<pre>
cd ftgl-2.1.3~rc5
./configure
make
sudo make install
</pre>
h2. Download the source
# To download the source code go to the link:
#* http://blake.bcm.edu/emanwiki/EMAN2
# Click on *"Main EMAN2 Download Page"*
# Click on *"Download EMAN 2"*, whichever is the latest release of EMAN.
# Scroll down to *Source* to download the *eman2.1beta3.source.tar.gz*
h2. Work with the source
# go to the directory with the source code
# extract the archive:
<pre>
tar zxvf eman2.12.source.tar.gz
</pre>
# go into directory
<pre>cd EMAN2/src/build</pre>
# start configure script:
<pre>cmake ../eman2/</pre>
#* 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.

h2. Set environmental variables
h3. bash
<pre>sudo nano /etc/profile.d/eman2.sh</pre>
<pre>
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
</pre>
h3. c shell
<pre>sudo nano /etc/profile.d/eman2.csh</pre>
<pre>
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
</pre>
h2. Install MyMPI
* First, add the openmpi module so that MyMPI can find it.
<pre>
module add openmpi-i386
-or-
module add openmpi-x86_64
</pre>
* 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:
<pre>tar zxvf pydusa-1.15es.tgz</pre>
* go into directory
<pre>cd pydusa-1.15es</pre>
If you are on a 64bit machine, you may have problems with the code finding the numpy headers:
<pre>nano configure</pre>
find the line:
<pre>
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"
</pre>
and replace it with:
<pre>
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"
</pre>
* Configure:
<pre>
setenv MPIROOT /usr/lib64/openmpi
setenv MPIINC /usr/include/openmpi-x86_64
setenv MPILIB ${MPIROOT}/lib
setenv MPIBIN ${MPIROOT}/bin
./configure
</pre>
<pre>
export MPIROOT=/usr/lib64/openmpi
export MPIINC=/usr/include/openmpi-x86_64
export MPILIB=${MPIROOT}/lib
export MPIBIN=${MPIROOT}/bin
./configure
</pre>
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:
<pre>
configure: error: Unable to find mpicc! mpicc location can be specified with --with-mpicc
</pre>
* compile the source:
<pre>make</pre>
* copy the mpi.so to site-packages with a different name:
<pre>
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
</pre>
* create a wrapper around the wrapper:
<pre>sudo nano /usr/lib64/python2.6/site-packages/mpi.py</pre>
<pre>
import ctypes
mpi = ctypes.CDLL('libmpi.so.1', ctypes.RTLD_GLOBAL)
from mympi.mpi import *
</pre>
This needs to be done to avoid the error:
<pre>
python: symbol lookup error:
/usr/lib64/openmpi/lib/openmpi/mca_paffinity_hwloc.so:
undefined symbol: mca_base_param_reg_int
</pre>
* test 1:
<pre>
python -c 'import mpi'
python -c 'import sys; from mpi import mpi_init; mpi_init(len(sys.argv), sys.argv)'
</pre>
* test 2:
<pre>sxisac.py start.hdf</pre>
(Note: start.hdf does not need to exist, if it does not exist then it should exit with file not found)
h2. Test to see if code works
see http://blake.bcm.edu/emanwiki/EMAN2/FAQ/EMAN2_unittest
<pre>
cd EMAN2/test/rt
./rt.py
</pre>
h2. 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:
<pre>
from mpi import mpi_init
ImportError: No module named mpi
</pre>
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.
