Triple & Quadrupole points

[NikitaSakharov]

Hi everyone!

I'm starting to work with triple points in my ebsd data and the first thing I've read here https://mtex-toolbox.github.io/TriplePoints.html was that I need to convert quadruple points to triple ones using appropriate option during grain reconstruction.

So I have some questions regarding these points and their convertation.

What if I do not use 'removeQuadruplePoints' option dirung calcGrain? What kind of error I'll get?
How can I see if there are any quadruple points in my dataset (or even points where 5 or more boundaries meet)?
What is the convertation procedure? I mean what does MTEX do, when we reconstryct grains with 'removeQuadruplePoints' option on.

Many thanks for the help!
