Thank you for the responses.
The RODFT requires with "CGMIN" . But the frequency calculatios were not possible with this option. My attempts to perform frequency calculation by removing this keyword was also unsuccessful. The options I tried for getting frequencies were as follows. As I mentioned both of these options were unsuccessful.
Thank You.
