Working with Files

SamIam supports opening files in six popular formats for defining Bayesian networks: the Hugin .net format (v5.7 and v6.*), the Genie .dsl and .xdsl formats, the Interchange .dsc format used by the Microsoft Bayesian Network Toolkit, the Netica .dne format and the Ergo .erg format. The program also supports some of the special editing features of these file formats.

For Hugin .net files, SamIam supports editing and saving conditional probability table (CPT) values for discrete nodes, the structure of the network, and the appearance of the network.

For each of the other five file types, including Genie .dsl files, SamIam supports editing and saving only the CPT and noisy-or weight definitions. The types of nodes defined within the Genie program that SamIam understands are "chance" nodes defined by CPT or noisy-or semantics and nodes of type "deterministic." SamIam also understands the Genie definitions of nodes as "target," "observation", and "auxiliary," and the definition of states as "target" and/or "default," and Genie submodels.
