Supported formats of model files

Analytica supports two formats for saving models — the default format and an XML format. Both formats are text files, which are fairly easy to read. You can view and edit them in standard text editors and word processors. (See examples below.)

Selecting a file format

Analytica normally saves a new model in the default format. You can change to the XML format in by checking Save in XML Format in the Save as dialog when you first select Save from the File menu, or whenever you select Save as. It remembers and reuses the format you select in future sessions.

Sample default file format

The default format lists each object starting with its class and identifier. Each subsequent line contains an attribute name, followed by “:”, and the attribute value. Here is part of a sample model file in the default format:
