Check Topological Magnetic Mat.

Given a file that contain the eigenvalues at each maximal kvec of a magnetic space group, the program gives the set of irreducible corepresentations at each maximal kvec.
Then, using the compatibility relations and the set of Elementary Band Representations (EBRs), it checks whether the set of bands can be expressed as linear combinations of EBRs.
This (selfexplanatory) file shows the format of the file to be uploaded in the menu on the right:
