Alright, we'll get to the bottom of this.
This is a list of what I do (which is clearly NOT working).
(1) open the .VTK file I emailed you.
(2)click apply
(3) I cannot select the calculator filter right now in the GUI hence
(4) I apply a gliph filter and set the radius to 0.1
(5) I can now apply a calculator filter. I leave the defaults and
write 1 in the empty space before applying it
(6) nothing changes in the snapshot apart from the color
(7) select again gliph filter, set sphere to radius 0.1 and click
apply (In the "scalar" field I now read "Result", so I thought
Paraview somehow had info about the previous filter I had applied),
(8) Now everything is red and I have no idea of what I should do.

What am I doing wrong?
