For a parameter estimation run on simulated data (i.e., when no observational data is available), an injection-file line is required in your config.ini-file pointing a dat or json injection file. The injection file itself contains a list of values for each source parameter (such as masses, spins, distance etc.) and is used to generate a gravitational-wave signal for a particular source (e.g. Binary Neutron Star).

To generate an injection file, NMMA provides the command-line utility nmma_create_injection. This generates a json style injection file by drawing from a prior file. The prior need not be the same prior used for analysis. As an example, the file below specifies a prior for binary neutron star system with aligned spins.
