Greetings:

I am experiencing this type of error when I try to run PSPW calculation:

------------------------------------------------------------------------

simulation_cell_input: unknown directive        0

------------------------------------------------------------------------


I am not sure what I am doing wrong. Can you give me some advice.

My input file includes the following info:
