Transpositions in my Opening repertoire

Sort:

I decided to try my hand at creating a repertoire. It's a PGN with many alternative opponent responses. As it's gotten more complex, (ie confusing) I believe that I may have some lines that transpose.

I think I need a software that will look at all the lines and output the FEN for each position to help me identify where the transpositions (the FENs would be duplicates). I could then go to those lines, collapsing them back into a simpler tree.

Is there a software that does this? I've looked at openingtree and chesstree....not quite, but there is some value add. Chesstree tells me that my repertoire is linear (I loaded my white repertoire to test this) and a video I watched on openingtree indicates it can find transpositions by analyzing games played, it doesn't seem it can do it from a PGN(???)

Suggestions anyone

Chesstree helped me find that I had 2 move options in my prep, which is undesirable, I need to simplify. It also showed me that I have 16 moves in a line, which is too much memorization and needs to be trimmed.
