[Ifeffit] How to select important MS paths in wurtzite?

[Mauro Rovezzi]

OK guys thanks to you all for the answers.

The scope of my question was mostly to add some knowledge-base on these
"selection criteria" and have a survey on your preferred rules of thumb.
In my case I also use the amplitude and the ss+collinear+triangle
approaches. I also agree with Bruce that Artemis has a great
visualization tool for selecting/understanding paths contributions.

To answer to Scott question:

I prefer to keep paths number small because moving from model compounds
to unknown samples, theoretical models will sum up and consequently the
respective number of paths/parameters will increase enormously.
