retrieve indices of true values

I have a data tree, with every branch consisting of 50 boolean items (true/false). I would like to retrieve all indices of true values, from every branch. I am sure, that it is very simple, but I still can't figure it out.

Thanks

Cheers

cześć :D

najprostsze rozwiazanie to:

komponent list length (podłaczamy do tego drzewa)-> nastepnie komponent series (długości z drzewa jako wejście C)-> equality (gdzie jako A dajemy drzewo a jako B pojedyncza wartosc true lub false) -> ostatni komponent to cull pattern (lista L to bedzie drzewo z wyjścia series, P to jest pattern z wyjścia equality).

napisze jeszcze po angielsku, bo to dość przydatne rozwiazanie :

solution in english :

workflow which will generate such a parallel data tree of indices consists of 4 components. first of all, take a "list length" component and connect it to your datatree. then use series (connect list length to C input) to generate all indices. next step is to cull indices which are not true (or false). you should use "equality" component and provide as A your primary datatree, as B one value (true or false). last step is to cull indices with pattern obtained with equality, use "cull pattern" to achieve that (data tree from series as list, pattern taken from equality).
