FGT is a tool to analyze rock fold geometry in 2D. It estimates material properties and shortening. It is developed in Matlab and compatible with Matlab versions from 2014b onwards.
The algorithms used in FGT are documented in the Journal of Structural Geology article: "Fold Geometry Toolbox - Automated determination of fold shape, shortening, and material properties" by Marta Adamuszek, Daniel Walter Schmid, and Marcin Dabrowski, doi:10.1016/j.jsg.2011.06.003 .
