Hi,
I understand “selection” is a very popular thing in root, such as:
tree->CopyTree(YourSelection);
The selection is “char *” defined such as “myleaf >= 0.5”. However, sometimes I don’t know 0.5 ahead of time, I have to calculate it and then give it to the selection. How can I realize that? What I tried:
float mycutvalue = 0.25*3;
tree->CopyTree(“myleaf >= mycutvalue”);
Of course, this is not working. Any hint?
Cheers,
Zhiyi.
