Does anyone know where to change this, the IA tree shows score/depth and it seems max depth is 63. How to increase it to allow deeper analysis to reach the IA tree?
Thanks!

I need to understand your problem. Are you doing infinite analysis and you want to increase the max depth?

The IA tree displays only depths up to 63 at least in my Aquarium. Analysis in certain positions can reach 70 or even 80. This does not get saved in the tree, only the analysis scores up to depth=63

You must have a very powerful system. How many threads do you assign to your engine.

32 core

It's just the recorded depth that has a maximum of 63. The evaluation in the tree keeps getting updated beyond that. If you analyze to depth 68 and the evaluation at that depth is +3.22, then that's the evaluation which is stored in the tree (not just the evaluation at depth 63).

Hmm. I am not sure the score does not get overwritten down the line as you perform IA. I have an example I can show of an analysis with depth 77 on move 45 (45...Bxh4), the tree should display a future move 47 with a depth of 75 (Rh7) but instead it shows a different move (47.Rbd7) when I allowed IA on that new position to a depth of 53...

It has been my experience that the IA value is updated by the Sandbox or IDeA, when doing various different things.  However, it has always been somewhat chaotic and inconsistent.  There does not appear to be anyway to force it to update or change to a value the engine has calculated.

To be precise I was referring to the stockfish IA tree.

Well, then I am clueless.  As I don't use the individual engine trees.
