Hi everyone, I have stacks of images with 4 different channels (the 4th is
opened in grey) and I want to make a selection to copy and paste in a new
image, conserving the 4 channels. The problem is that if I work with these
multi-tiff or similar when I make a selection I only copy the present
channel, so in order to copy all at the same time I used to save in .png the
focal plane of interest, and there make the selection. However when I do
that saves the image in RGB so when my macro separates channels it will be a
mess...
any idea how to save a selection keeping the 4 channels?

Thanks,
