Question about math on slice in stack ves in a hyperstack

[Cammer, Michael-3]

When doing math on a simple stack, a window pops up asking whether to operate on the slice or on the whole stack.


When operating on a hyperstack, however, the math is immediately applied to the entire hyperstack.  Is this standard behavior or a bug?


By using a macro command with a  hyperstack

  run("Multiply...", "value=0.5 slice");

operates exclusively on the single slice, channel, frame that is active.


Also, are there plans for the future that we could also specify operating on just one channel?


Thank you!

This is the expected behavior with hyperstacks in “Composite” mode. Use the Image>Color>Channels tool to switch to “Color” or “Grayscale” mode and you will get the dialog asking whether to operate on the slice or on the whole stack.
