This was a really long month. I have been trying to resolve an issue of incompatibility of three coordinate systems: the one in which Euler angles of misorientations are computed, the one in which x and y coordinates of .ang data files are given and the last one which is used in the external software used for reconstruction of surface meshes of grain boundaries, the software interprets the first two somehow... I spent hours carrying out various tests hoping to end up with correct shape of grain boundary distributions. Meanwhile I improved many features of my program making it more user-friendly.
