EBSD Data is stored in the class EBSD and in the latter the class grain holds modelled grains. The following mindmap may induce a general idea analysing EBSD Data with MTEX.

Grains are a basic concept for spatially indexed EBSD Data. With grain modelling comes up the possibility of getting more information out of the EBSD Data - e.g. fabric analysis, characterisation of misorientation

Visualizing EBSD Data is a central part to understand the crystallographic orientation of a specimen. The most naive way to do this is by plotting the individual orientations as poles in pole figures or spatially indexed points in some map with colorcoded orientations. Moreover one gets with grains the possibility to take a closer look on grain boundaries and depending on the case, even in the internal structure of the grains.

Estimating ODFs from EBSD Data is also interesting when one has large datasets with and the plotting of individual measurements produces crowded pole figures. Nevertheless the selection of the optimal halfwidth for different dataset is a difficult question, in particular in matters of grains.
