many software packages probably can do that, but at the same time they 
might not be able to handle the different microscope file formats. Doing 
all the conversion steps manually is ok for 1 or 2 images, but becomes 
rather cumbersome if you have to do it for several hundred images.

Exactly. Overlaying the height image in Gwyddion 3D view with a TIFF 
image (or at least with separate RGB channels).

yes, yes, yes! ;-)

Kind regards,
