Hi, thank you all for your very helpful comments. Below some additional details.

It's the roughness from the x, y, z positions. So some interpolation/spline would probably be the best solution. But I guess then the data also needs to be interpolated ?

I do indeed have Richard Gillilans' package successfully installed. The funny thing is that I get it to work without problems for Linux, but not for Mac OS X ..

But in the example nets that come with CMSP there are no examples using FancyRibbons :( And when I try to do it on an imported structure, I get ERROR: FancyRibbon: Missing data: input has no data component Chris, would you mind sending me one or better several of your examples where you have used FancyRibbons ?
