This module returns one of the possible shortest paths between the sources defined in the program configuration ("Sources and bounds configuration" module) and an user defined objective compound. This algorithm takes into account the stoichiometry and bound of the reactions. It's input file is a SBML file and the output subnetwork won't contain loops.
It creates a new SBML file that can be visualized selecting it in the left side of the screen and using the right button of the mouse to select the options "Visualize".
The initial or unprocessed SBML models don't have contain any graph so they can't be visualized.
When the new model is saved inside a project, its comments/information and its graph will be saved with it in separated files. The SBML file can be also saved as a single SBML file to be used in other software by selecting the option "Save model in a file" which appears when the model is selected and the the right button of the mouse is pressed.
