Hi All,

I am trying to remove instrument response but I am getting these errors.
Any one can provide me solution for it ?

Cannot determine normalization status because NormFreq is outside

Response appears to be Un-Normalized.
Waveform appears to be scaled.
Wfdisc calib value is (1.000000).
Waveform multiplied by 1.000000 after deconvolution.


Thanks

    Hi Mohit,

    Are you using the last version of sac (101.6)?
    Can you provide copy of data and response files?

    I try the transfer function command with my data and resp files,
    and all works OK.

        Thanks for your reply Milton. I am using sac version 101.4. I am also
        attaching the sample sac data file along with its RESP file for your
        testing. Please let me know if it works on your version of sac.

    I think you are using an old version of SAC, as the message you cite were removed in v101.5. The current gversion is v101.6.
