Hi all could you guys give me some idea on this:

I have 10 multi-band (multispectral) images. For each and every multi-band image, I would like to extract a particular band (say, BAND 3) and then to stack them together into 1 multi-band image (which consists only of BAND 3 from the 10 multispectral images).

Anyone knows how could I do this? I believe composite bands have to be used for stacking, but what about extraction?

Thanks in advance.

Regards
Ben
