Model files are stored in XML format for transparency (more specifically, a "pretty" (or clean) XML format using Xstream http://xstream.codehaus.org/
The XML format is used for Open, Add from File, Save, and Save As file operations
Extension .apn is used by default, but other extensions can be opened (e.g., .xml) if all files option is used in file chooser
Diagrams images are saved in scalable vector graphic format (SVG) for high quality pictures reproduction (and further editing)
Save Charts option creates a XLS file based on a template that plots sensor reading history (see picture). Both the chart and data (see picture) can be further edited in Excel. Options are shown below (this menu is only available after Monte Carlo simulation is completed)
Save Full Report creates a XLS file where all properties of the net are organized by tabs. This is useful for documentation and verification of the model, as well as for post processing from the results that are contained in the last two tabs. The following tabs are created: The first "Main" tab provides a short summary of the run, including the time stamp of the run, the source file, and the APN version. The next eight tabs provide detailed listing of all the objects of the model (i.e., Transition, Places, Joints, Triggers, and Tokens along with the associated parameters). Finally, the last two tabs document the results from the sensors. The "Sensor" tab summarizes the results from each sensor along with its settings. The last ("Time History") tab, introduced in APN 2.1.0 version, provides the time history for each sensor: in the case case of the regular sensors, the probability values are reported, while for the mean sensors mean values are provided.
Chart report optons shown when "Save Chart" is open. Up to five curves can be included in a single chart. First column names correspond to the legends of the curves (set by default as the place names the place is selected in the second column). Only the places with sensors appear in the selection options for the second column. Once the place is selected in the second column, the sensor from the place can be selected in the third column. The fourth column shows whether the selected sensor is mean or not (this column cannot be edited here since this choice is made while setting up the sensor), the fifth column provides an option between the "hits" (number of times in the simulation when a given threshold is crossed during the last time step) and probability that a threshold is crossed for regular sensors. For mean sensors the choice is between displaying mean value or the variance for the number of tokens in a given place at a given time step. Selecting "Diff" allows to see the normalized rate of change of the quantity of interest (if we evaluate the probability this provides a PDF chart).
Once the report is configured it can be saved and loaded later as needed, when the model is rerun (this assumes that the sensors of the model were unchanged).
As of Version 2.1.6 simulation trace (the history of tokens travelling through the net) is automatically written into the matlab file "trace.mat" the details are described in the Simulation Options.
