Hi everybody.

I am making an opening book and want the engine to play various lines against me at the same frequency as humans play them.
I created an opening book from Chessbase and imported it into Aquarium, and want to globally change the play percentages to be the same as the total % shown in the picture.

I know how to do it manually one move at a time but it would take more than my remaining lifespan to do it that way.
Is there some way to edit the CTG or AQT file? A script maybe?

If you want an engine that plays like a human, you can try the Lc0 Maia series of engines. They are based/trained on human games played at Lichess. For example, Maia 1100 is based on games between players rated at 1100, etc.

The widebook pretty much does it except you have to change the weight for cap and eval values to 0.
1. Make a copy of the widebook tree and give it another name.
2. change the weight values of this new tree as follows
a.  make sure it's a clean copy of the orginal widebook
b. set eval weight to 0
c. set Beval weight to 0
d. set cap weights to 0

The Play % column will reflect the relative percentage of games in the totals column. (It won't be too much different from the original Play% numbers)
The Play % numbers are close to tournament game percentages, but also reflects the editorial choices of the book author.
Once you set up your book, you can use choose a different reference tree for the totals column to suit your personal preferences.
