    The correspondences between ReprType codes and the description of representations are given in the textual file TTOReprTypes.txt.

    All .tto files have to be copied into a separate directory (/TTO by default) within the ToposPro folder. The path to TTO collection can be changed with the ToposPro DBMS in the System/TOPOS Parameters/Paths options. Do not forget to copy TTOReprTypes.txt and put it into TTO folder.
