Hi Michael,

at least with the current daily build (1.54s8), I cannot see this issue. This is what I tried:

  run("Neuron (5 channels)");
  run("32-bit");

or, alternatively,

  run("Neuron (5 channels)");
  run("Make Composite");
  run("32-bit");

or (with a 4D stack):

  run("Organ of Corti (4D stack)");
  run("32-bit");

Neither of these switch to grayscale.


Michael

Is this a new behavior or something I just didn't notice before?

When we are looking at a 4 channels 16 bit hyperstack in color, changing the type to 32 
bits makes all the channels grayscale.   run("32-bit");

Is there a way to keep the original LUT of each channel when switching modes 
without having to write a macro where we get the LUT of each channel and set it 
after the conversion?

Thank you.
