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

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