h2. Overview

Appion  is a "pipeline" for processing and analysis of EM images.  Appion is integrated with "Leginon":http//leginon.org data acquisition but can also be used stand-alone after uploading images (either digital or scanned micrographs) or particle stacks using a set of provided tools. Appion consists of a web based user interface linked to a set of python scripts that control several underlying integrated processing packages. All data input and output within Appion is managed using tightly integrated SQL databases. The goal is to have all control of the processing pipeline managed from a web based user interface and all output from the processing presented using web based viewing tools.  

The underlying packages integrated into Appion include "EMAN":http://blake.bcm.edu/eman, "Spider":http://www.wadsworth.org/spider_doc/spider/docs/spider.html, "Frealign":http://emlab.rose2.brandeis.edu/, "Imagic":http://imagescience.de/imagic/, "XMIPP":http://xmipp.cnb.csic.es/, "IMOD":http://bio3d.colorado.edu/imod/, "ProTomo":http://www.electrontomography.org/, "ACE":http://emg.nysbc.org/projects/ami/wiki/ACE, "CTFFind and CTFTilt":http://emlab.rose2.brandeis.edu/, "findEM":http://nramm.scripps.edu/software/findem/, "DogPicker":http://nramm.scripps.edu/software/dogpicker/, "TiltPicker":http://emg.nysbc.org/projects/tiltpicker/wiki, "RMeasure":http://emlab.rose2.brandeis.edu/, "EM-BFACTOR":http://www.ual.es/~jjfdez/SW/embfactor.html, and "Chimera":http://www.cgl.ucsf.edu/chimera.  These packages must be acknowledged by appropriate citations when used within Appion. Appropriate citations are provided on the individual pages in Appion as well as "here":http://emg.nysbc.org/projects/appion/wiki/Appion_citations.
