Hello,

I have been running into trouble when I attempt to calculate the vibrational modes of an optimized CO2 molecule (PBE functional, DZVP basis set) in CP2K version 6.1 using the "VIBRATIONAL_ANALYSIS" keyword (error attached below). 

Why this is happening? I am unsure if this is because of the linearity or symmetry of the molecule, I have tried to change the symmetry but I still receive the same error (attached below) within 2 seconds of the calculation run. 

I have also attached the input and output files in this message. Any help will be appreciated. 

Thanks in advance.

Anantha
