If you like to include other species than listed above, you have to include your own species_definition.r file in your parameter file. To do so, uncomment the following lines from your .par file:

SPECIESFILE = "my_species_definition.r";

As a basis you can take the original file from your picmc installation at “/your/picmc/path/scr/species_definition.r” and adapt it to your needs. The new file should be placed in the same folder as your parameter file.
