There are several ways to export data from EPE
- Standard export, which saves all map information
- SBML level 1 version 2 export, for metabolic maps created with EMP context.
- RTF export, for metabolic maps.
From the
File->Export menu item you should see the following dialog box:

For standard export, navigate to :
Other->Export to XML and click Next. This leads to the following page:

In the tree-viewer select the folder or map you wish to export, and use the browse button (arrowed) to choose your destination directory.
Then click Finish.
Export can take a long time if you are exporting many maps so you can export it in the background.
SBML export currently is implemented for metabolic maps (EMP context). In order for a successful
export to occur, EPE needs to know where to find your data.
The map screenshot below shows that
- The species name field must be defined in the compound name property,
- The port type defines whether the species are reactants (green, source) or products(target,red).
- Directionality is determined by the arrows, which are manipulable from the map context menu when a process is selected using the
"Decorators.." commands.

Empty compound names will generate an error. Non compliant SBML names are converted to an SBML acceptable string, and
the real name stored in an annotation element.
Folders can be selected - however any maps in the folder that are not EMP context will cause an error dialog to pop up.
For best results, keep metabolic maps in their own folders prior to export.
