h4. Sinedon.cfg

At AMI, you do not normally need a sinedon.cfg file, but if you have your own testing environment you will need one.

h4. Web page

At AMI, put myamiweb into your ami_html directory and it will be available on both cronus3 and fly as http://cronus3.scripps.edu/~username/myamiweb/

You will need to run Eric's web setup wizard to get it working: http://cronus3.scripps.edu/~username/myamiweb/setup/

h2. Organization of the Python programs

We have two major folders in the appion folder:

* appionlib: contains libraries, a collection of common functions that are needed by more than one python program, e.g., ssnrResolution, averageStack, and lowPassFilter.

* bin: contains the programs that take command line input, e.g., makestack2.py, templateCorrelator.py, maxlikeAlignment.py

Other useful directories:

* pyami: a collection of common functions to both appion and leginon, save MRC file, save SPIDER file, etc.

h3. Most important python files:

* source:trunk/appion/appionlib/appiondata.py: describes how the database is put together, if you need to add a new column go here
