TTO (Topological Types Observed) collection matches topological types of abstract nets and graphs collected in the TTD with examples of real crystal structures.

Total entries: 1,795,772
Number of counted structures: 689,984
The diversity of topological types: 46,143

TTO (Topological Types Observed) collection matches topological types of abstract nets collected in TTD with examples of real crystal structures. TTO files have .tto extension and contain the records of the following format:

RefCode - the Reference Code of a particular structure;
Dimen - dimensionality of underlying net;
Z - number of nets;
TopType - topology of the net (its code in TTD Collection);
ReprType - code of representation type of the structure.


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

ATTENTION! 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 (28.04.2013) and put it into TTO folder.

Having TTO collection the user may now perform the following operations:

Find all topologies for all representations of a particular crystal structure.
Find all structures with a particular topology of underlying net.
Find all structures with a particular topology in a given database.
