| SPT (single particle tomography) capabilities are relatively new in EMAN2. They were inspired by Michael Schmid's studies on sub-volume averaging (mostly on viruses), and a stubborn student insisting on doing extensive sub-volume averaging on chaperons. | The SPT page has move to http://blake.bcm.edu/emanwiki/SPT/Spt |

| This session will cover the beta version of a small fraction of the SPT capabilities EMAN2 will eventually make available. | This is just an archaic page with the version of the tutorial used in the EMAN2 Workshop in March 2011. |

| The session will cover: \n1) SPT processing through EMAN2's workflow: e2workflow.py \n2) Sub-volume extraction from tomograms using e2tomoboxer.py 3) "Preparation" of extracted particles for alignment (for a myriad of reasons, it is NOT recommendable to align and average sub-volumes directly after extraction). 4) Reference based alignment and averaging |

| All necessary software is provided as part of EMAN2. If you don't have EMAN2 installed, you can download the most updated version (for your specific platform, Windows, Linux or Mac), from here: http://ncmi.bcm.edu/ncmi/software/counter_222/software_86 |

| We have prepared sample data for this tutorial. The tomogram in the link below comes from a tilt series of epsilon15 virus particles in vitro, recorded using Zernike phase-plate technology: |
