Upload CIF file and get the topological type of your crystal structure.
Drop CIF File with one structure here
Maximum file size - 2 MB
The upload limit of CIF files is no more than 10 structures per day for each user.
A video lesson of how to work with the TopCryst service is available
We use the full and actual version of the
collection to determine the topological type.
