Agent Positions at frame / Cull Tree branches with certain index value

Hi everyone,

First off, I am not very familiar with trees and data organization but wanting to learn. I have a .csv file I've exported out of a pedestrian simulation software. It details an agent's position relative to a frame value as shown in the "Data_Location" Panel. There are multiple agent positions for every frame value. I want to find all branches with a specific value at index 0 (for example "455") and then plot the x,y,z values at index 2,3,4 for each of those branches.

Any thoughts on how to do this?

Thanks in advance!
