Dear Mahmoud, occupation='from_input' refers to the occupation of the Kohn-Sham states, not to the occupation matrices of the Hubbard part. As far as I know there is no flag to read those matrices only. However the code reads them when you restart a DFT+U calculation from an existing charge density. so I would try instead to set startingpot = 'file'.
