Appion

uploadRelion3dRefine.py requires at least matplotlib version 1.5.1 in order to render the hex plots. I had issues getting to this version in CentOS6, but here is what I did to get it working:

sudo pip install pip==8.1.2
sudo pip install setuptools==36.2.7
sudo easy_install -U distribute
sudo pip install numpy==1.5.1
sudo pip install numpy==1.6.1
sudo pip install matplotlib==1.5.1
