Thank you both! Exactly what I needed

Is there any way to split channels for colors and recombine them? Ideally I'd like to be able to take an image, split it into red, blue, green, and alpha layers (each one appearing as a greyscale image), to be able to mess around with each one, and then recombine them into a full color image with transparency. Alternatively, any way to just be able to take a greyscale image that represents the transparency and merge it into the image would be fine. Thanks for any help you can give
