No, this is no problem. Indexed images consist of a 2D index image,
ranging from 1 to NC, and a colormap, which is NC x 3, where "NC" is
the number of colors in the image.  Indexed images are totally
different from intensity images, because the index image is really an
index into the colormap, so it must be an integer number.

The errors tell me that you are probably using animal 0.10.2. But
candidate 2 requires animal 0.10.4. Sorry, I should have said that...

cheers,
