Dear SAC user,

I am trying to set the theoretical travel time in sac head.
But I am get error message as:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
taup_setsac -mod iasp91 -ph Pdiff-1,P-1 2012.239b.20.57.58.ADK.sac.z

I did not understand why I am getting this error. Error say that it dont appear to be a sac file. But it is a SAC file
with complete header information. Earlier I have set the time with out any problem. But now I did not understand where my problem lies.

Header information:
