From: Non-homogeneous models of sequence evolution in the Bio++ suite of libraries and programs
Model specification in BppML and BppSeqGen. A general file format is introduced to allow for the user-friendly description of virtually any non-homogeneous model. The tree shows the nodes identifiers, which can be obtained from the programs or defined by the user in its own program. Each case presented here corresponds to a particular model in figure 1, and was labeled accordingly. Each parameter can be fixed to a specific value or optimized with BppML.
