Hi, what are the program parameters? From the error message I'm guessing that you use the toFilecommand without the output-path parameter. Could that be the case?

This are the program parameters
java -jar rmlstreamer.jar toFile --mapping-file C:/Users/Usuario/Desktop/TFG/Mapping/ComunidadMadrid/Meteorologicos/map1.rml.ttl --output-path prueba.nt
Its gaves me this error:

There is indeed an issue with relative paths that's not entirely fixed yet. In your case, it might help to add the "current directory" to the output path: --output-path ./prueba.nt or, if that doesn't work, the absolute directory.
