Hi,
 You can split the channels and then select the channel you want using the
imageID.  A Macro that looks something like this

run("Split Channels"); //split the channels
blue = getImageID(); // get id of blue image
red = blue+1 ; //assign ids
green = blue + 2; //assign ids


should get you the individual channels.
then you can use selectImage(ImageID) to get the channel you want..


selectImage(green);

and then save it..


hope this helps...
