there is a specific error that comes up just for this one material (anthracene) when using "extract_forceconstants"
ERROR
exit code 4: symmetry error Bad operation singlets occurs in file: lo_symmetry_of_interactions_nullspace.f90
occurs on line: 643
active rank: 0 out of 1
ERROR STOP 4
I refined the structure (either ase_geometry or refine_structure) and the correct space-group is found and even tried different unit cell conventions but the error persists. It does not occur for any other material I tried so far.
