The ideia of the separator is to pick something with the lowest
likelihood of appearing on the returned value. I also use linux and
didn't had a problem. It's weird that it doesn't work for you. Could
you please send the values that gave you the error?

Using strsplit is great. I didn't knew of this function, just tried
and works great. Will apply this change immediately. Thank you

This worked fine for me. Could you please give some data example to
replicate this? Thanks in advance

Actually I already sorted this problem by using fscanf instead. It may
be fixed on 3.4.0 (see octave bug #33330 here
https://savannah.gnu.org/bugs/?33330 ). The bug was actually an hack
to force compatibility with MatLab which seems to not deal very well
with pipes. The idea of using scale this way is that it allows to
generate a scale that can be used to select values and see the effect
on real time (to choose treshold values on a image for example). And
yeah, I should update my octave version.
Thank you for looking into this. It's good to have someone else
looking at it and commenting.
