I wonder if there is a free tool to get a file with stat about my games

[Uri Blass]

I want the following information for my games with white(the numbers in this post are not from my games but only an example for what I want)

1.e4 500 out of 900
1.d4 400 out of 900

1.e4 c5 200 out of 500
1.e4 e5 150 out of 500
1.e4 e6 100 out of 500
1.e4 c6 50 out of 500
1.d4 d5 200 out of 400
1.d4 Nf6 200 out of 400

I want it to continue to 3 plies,4 plies and later when you stop it only when all the games are different so every line has 1 out of x.

The tool that I want is simply a tool that read a pgn and give me this output as a text file.

I have one such tool but it is based on ECO codes with a max of 5 characters.
