Check Topological Layer Mat.
Given a file that contain the eigenvalues at each maximal k-vec of a layer space group, the program gives the set of irreducible co-representations at each maximal k-vec. 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.

You can generate the "trace.txt" file in your own computer using VASP and this program (fortran).
