I am trying to visualize frequencies from a Orca Opt Freq job in Avogadro 2.0. When no symmetry labels are requested on input (default), the vibrations are properly displayed. However, when symmetry labels are requested (with the (UseSym keyword), the code does not display vibrations.
It seems to be an issue with the parser. If I remove the symmetry-aware labels in the output, the vibrations are shown.
Here you have sample files:
Without the UseSym keyword (vibrations displayed)
water_nosym.inp (254 Bytes)
water_nosym.out (157.6 KB)
With the UseSym keyword (vibrations not displayed)
water_withsym.inp (261 Bytes)
water_withsym.out (250.0 KB)
This post is related to ORCA Vibrational Frequencies from Opt Freq Jobs Missing?, where a similar issue was described, but it seems not to be solved.
