Fine tuning

[Jennil Thiyam]

I want to perform fine tuning over ben.traindata by adding one character.  It is written that for fine tuning what we need is to add only the desirable characters to langdata/ben/ben,training_text. but in the folder 'ben' it consist other file also like ben.config, ben.params_model,ben.word.bigram, etc. so my question is, only by adding the character in ben.training_text, will the model work???
