Select CHOP

The Select CHOP is your primary tool for routing and filtering data channels. It extracts specific channels from any other CHOP in your project, even if that CHOP is inside a different component.

Why Use It?

Instead of routing long, messy wires across your network (or between different COMPs), you use a Select CHOP to grab the data you need exactly where you need it. This keeps your networks clean and modular.

Core Parameters

1. CHOP: The path to the source CHOP you want to pull data from.
   • Example: ../math1 or /project1/audio_analysis/out1
   • Tip: You can drag and drop a source CHOP directly onto the Select CHOP to automatically fill this parameter.
2. Channel Names: The specific channel(s) you want to extract.
   • You can type channel names directly (e.g., tx ty tz).
   • You can use wildcards (e.g., * to select all, chan[1-3] to select 1, 2, and 3).
   • Tip: Use the dropdown arrow next to the parameter to see a list of available channels from the source CHOP.
3. Rename From / Rename To: A powerful way to instantly rename channels as you select them.
   • Example: Rename chan1 to speed.
   • Wildcards work here too: Rename * to mouse_* adds a prefix to all incoming channels.

The Select TOP

There is an equivalent Select TOP that works exactly the same way, but for grabbing 2D image data/textures from another part of your network without drawing long wires.
