Now ,I want to modify the "-ceplen 13" to any number what I want,do you think the Sphinx will complete?

Maybe Sphinx would do with  "-ceplen 13" and other will be wrong!

You can use another number, but remember that it must be smaller than number of filters/2 (usually 20) and bigger than 5. Many researches state that there is no much difference.
