Hi Keith, The foo.traindedata is not existing but do you mean : the trainedata I want to train ex: hye.traineddata ? In my case I should add a new character in the hye.traineddata It seems that I can do this using the option 2 ! But how ? Which command should I use to execute this function and what does mean this process ?
