Dear all:

I tried to calculate the Raman tensor of siliver bulk.
I got an error inthe log file,showed below

chkinp : ERROR -  
The value of occopt is found to be 4 
This is not allowed in a non-linear response calculation.
Action : put occopt = 1 in your input file

But siliver bulk is metallic, the value of occopt should be 3~7.
Dose it mean that I can't cacilation the Raman tensor of metal?

Thanks for your help.
