What does "init_wfc=file" mean in LCAO?

[Qianruipku]

Details

In PW basis, init_wfc=file means reading WAVEFUNC*.dat to init psi.
But in LCAO, it executes read_wfc_nao function.
The init_wfc parameter needs to be clearly explained in the documentation, as the current documentation is incorrect.

In the lcao basis set, the read_wfc_nao function can be executed, which mostly ba used when calculation = get_pchg and get_wf, autosetting init_wfc = file.
