Open 4-channel GeoTIFF

I have been trying to open a 4-channel GeoTIFF file in ImageJ. It always opens it as a RGB image, i.e., just recognizing the first three channels. Is there a way that I can open the GeoTIFF file with all four channels visible either in ImageJ’ GUI or using ImageJ’s APIs? Thanks!

Try to use the Bio-Formats library. For instance I could open Landsat 8 images with it without problems.

That does work out nicely. Thanks for your help. @Bio7
