Appion

h1. Cluster job overview

From the user perspective, a refinement job includes 3 parts:

# Preparation step

** prepares any data that is needed for the method to be run

** includes modifying a selected stack to be in any required format

# Run step

** User selects which cluster they would like to run the job on

** The job file is built and submitted to a queue

# Upload step

** Results are converted to a format that Appion accepts

** Converted results are uploaded to the Appion Database

From a programming perspective, the following pieces of code need to be written:

# GUI prep step launch form

# Python prep step run script

# GUI run step launch form

# Python run step run script

# GUI upload step launch form

# Python upload step run script

# GUI results viewing page

Many of these pieces use the [[Object_Oriented_Programming|object-oriented programming]] feature of inheritance to create base classes that take care of common functions.
