How to apply a data tree structure to a flat structure

Hi

I am struggling with the path/branches.

I have two sets of data with the same amount of points. First data structure is flat with only one path of 2244 points, second is structured by 204 path each containing 11 points. What I would like is to apply the data structure of the second list with the 204 path to the datas of the first list.
I guess it should be possible when the amount of items in the structures are the same.?

I hope you can help me out

Stig

Either use a Flatten component or toggle the Flatten option on any parameter that receives the data. Going the other way (i.e. converting your list of 2244 items into 204 lists of 11 items each) is more complicated but also possible.

Hi,
Normally it’s a problem.
But if you have the same amount of elements on each path,
what I normally do is a series of a series, like the example.

Regards,
Carlos

Hi all, before 06.0055 I used to apply Carlos' method, but I wanted to give a try to the path mapper component, which seems to be perfect for these issues. I eventually succeeded although I did not understand why I had to apply a strange "-5" to the destination formula (see attached image)... anybody has a clue?

(i-1)/3
(i-2)/5
(i-3)/7
(i-4)/9
(i-5)/11
....
(i-n)/2n+1

And you can't make it work for even numbers; ▶ Reply to This
