Yeah, my g'mic example had a semantic mistake, sorry: it should have 
read something like:

gmic 32bit_float_input_with_range_to_65535.tif -/ 65535 -o 32bit_float_output.tif

...meaning, GIMP opens the 16bit integer stuff fine, it's the float 
format with an unexpected range that gives it trouble. There is a 
normalize operator ("-n 0,1") for g'mic, but as the g'mic developer 
points out, that could mess with the dynamic range, so using the divisor 
(-/) you can scale it appropriately. (E.g. -/ 255 if the original ranged 
over an 8bit scale.)

Will do! Thanks!
