Install EMAN¶

EMAN1 is a fundamental package used in Appion for general file conversion and image filtering.

Download latest EMAN1 (not EMAN2) binaries (currently version 1.9):¶

1. Go to the EMAN webpage
2. Click on (download) next to EMAN1
3. Scroll to Download 1.9
   • Note: For CentOS 6, you should download the latest nightly snapshot. (eman.daily.linuxcluster.tar.gz)
4. Click on Download 1.9 link
5. Select the appropriate package
   • we recommend using the cluster version of EMAN1
   • x86 for 32bit and x86_64 for 64bit machines
   • In this case, we would download the "eman-linux-x86_64-cluster-1.9.tar.gz"

• We have tgz files under Files tag of this website

Install EMAN¶

1. Go to download directory and unzip the tar file:
   

   tar -zxvf eman-linux-x86_64-cluster-1.9.tar.gz

2. Move the unzipped folder to a global location
   

   sudo mv -v EMAN /usr/local/

3. Run the EMAN installer, it sets up the EMAN python module (must be run from the EMAN directory)
   

   cd /usr/local/EMAN/
   ./eman-installer
   

Set enivromental variables¶

• For BASH, create an eman.sh and add the following lines:
  

  export EMANDIR=/usr/local/EMAN
  export PATH=${EMANDIR}/bin:${PATH}
  export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${EMANDIR}/lib
  export PYTHONPATH=${EMANDIR}/lib
  

• For C shell, create an eman.csh and add the following lines:
  

  setenv EMANDIR /usr/local/EMAN
  setenv PATH ${EMANDIR}/bin:${PATH}
  setenv LD_LIBRARY_PATH ${EMANDIR}/lib
  setenv PYTHONPATH ${EMANDIR}/lib
  

• And then add it to the global /etc/profile.d/ folder
  

  sudo cp -v eman.sh /etc/profile.d/eman.sh
  sudo chmod 755 /etc/profile.d/eman.sh
  
  - or -
  
  sudo cp -v eman.csh /etc/profile.d/eman.csh
  sudo chmod 755 /etc/profile.d/eman.csh
  

You may need to log out and log back in for these changes to take place.
