Hi, When you are using -c param, you need to provide gt.txt file names. The error in second case says that it didn't find and gt files from where it can build codec for your case. There are two things you can do:
1. If you know all the alphabets in your data, then simply create a gt.txt file and give it as -c 'abc.gt.txt', or 2. you can read all alphabets from your gt files as -c '*.gt.txt'. Hope that it will work :).
