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¶

To download the source code go to the link:
- http://blake.bcm.edu/emanwiki/EMAN2
Click on "Current stable version - direct link"
Go under the heading "Source" at bottom of page
Click to download the eman-source-2.xx.tar.gz file (as of August 2012, 2.xx is 2.06)

Work with the source¶

go to the directory with the source code
extract the archive:
```
tar zxvf eman-source-2.06.tar.gz
```
go into directory
```
cd EMAN2/src/build
```
start configure script:
```
cmake ../eman2/
```
- Note: alternatively you can run ccmake ../eman2/ and configure all the parameters
start compiling:
```
make
```
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
