Third-order interatomic force constants are not output.

[Second0507]

Hi,

I'm using ALAMODE to calculate the third-order interatomic force of Au. I need to get information on the third-order force constants in order to calculate the Au thermal conductivity.
However, the output PREFIX.pattern_ANHARM3 does not show the 3rd order force constant. What should I do, is it related to the high symmetry of the Au structure?

Thanks!
