Tree Branch Replacement

I cant for the life of me figure out how to replace a branch of a tree.

Lets say i have a tree

{0;0} n8

{0;1} n8

{0;2} n8

{0;3} n8

{0;4} n8

{0;5} n8

And i want to alter the data in {0;0} n8 and {0;5} n8 I can easily retrieve a specific tree branch, then modify the data, lets say to each have 6 items in their list instead of 8. the end resut i want is:

{0;0} n6

{0;1} n8

{0;2} n8

{0;3} n8

{0;4} n8

{0;5} n6

But i cant seem to get the "replace branch" componet to work

In reality i have a tree that consists of 108 branches, so exploding the tree and entwining (which is my normal work around) is impractical

any help is appreciated!

ReplaceBranch renames the branch index. If you had a branch {0;0;0} and wanted to have {0;1} instead, this would be your component.

For your problem: you normally have a logic, that is flexible enought to handle zero input. Say you want to delete the first and last item in the list. Then your logic could pass 0 and [listLength-1] in your branches {0;0} and {0;5} and use those for a CullIndex. For branches, you want to leave untouched, just pass no values.

I think i understand what your saying. But for my specific problem, im not trying to eliminate items in the list, i am taking the {0;0} n8 and completely changing the items in the list.
