MRMC uses the .tra file to represent a model's transition matrix. Depending on the model, the matrix contains transition rates or transition probabilities between states.
The file is a model-input file for MRMC's analysis of Markov chains and Markov reward models. It is used together with other MRMC input files when a model also requires state labels or reward information.
The format is intended for use with MRMC on Microsoft Windows.
Open the .tra file in MRMC on Microsoft Windows and select it as the transition-matrix or model input file for the analysis.
A text editor can be used to inspect the file, but it is intended to be processed by MRMC.
There is generally no useful standalone conversion for an MRMC .tra file. It should remain in the format expected by MRMC.
If the model is being moved to another analysis tool, use that tool's model-import or model-generation facilities and recreate the transition matrix in its supported format. Keep any associated MRMC label or reward data separately, because converting the matrix alone may not preserve the complete model.
