pwtools.pwscf.read_all_dyn

pwtools.pwscf.read_all_dyn(path, nqpoints=None, natoms=None, base='ph.dyn')

Same as read_matdyn_modes(), but instead of the file matdyn.modes which contains freqs,vecs for all qpoints, we read all dynamical matrix files in path, one per qpoint.

Parameters:

• path (str) – Path where dyn files live.

• nqpoints (int) – number of dyn files (e.g. 5 for “ph.dyn1”, …, “ph.dyn5” if base='ph.dyn')

• natoms (int) –

• base (str) – Basename of the dyn files.

Returns:

Same as read_matdyn_modes()

Return type:

(qpoint,freqs,vecs)
