Access individual channels on an image texture node

[AaronWPowell]

Is there an easy way to access individual channels in an AiImage node? For example, I'd like to be able to individually grab r, g, b, or a channels to use in other nodes, similar to selecting the "single channel" checkbox in the UI. I have a feeling I'd have to use the AtTexture API to do this but I can't find a good example to pull from. Any tips would be appreciated!

You have Start Channel in aiImage Node
0 = default, then you can put (1 or 2 or 3) to extract any channel
another way is to use aiShuffle Node

This is pretty straightforward. Thanks! Is something like the AiShuffle node the recommended way to extract channels when using the API directly with C++ or Python?
