Dear Friends;
I have writen into the SAC file after I pick AMARKER on the waveform.
My question How can I change pick if I made a mistake when I pick it.
I tried the following but the error given
I read the data which is consist of 3 channels
then I tried to change AMARKER of 3 channels
SAC> r OBN*
SAC> chnhdr AMARKER 212.24
ERROR 901: SAC programming logic error
SAC>
Are there any method instead of return raw data back to use.
Regards...
Murat

Dear Friends,
I read sac data and draw by plotpk p 1
then I pick p and s arrival on the data.
But I would like to save picked data to the SAC data header.
I mean When I open the data after I save even if I close the session of SAC,
I would like to see the picked phases on the waveform.
Could you tell me How can I do this.
Regards...
Murat

Hello Murat,
after you read a file into SAC, you can use the command SAC> listhdr (or
SAC> lh ) within SAC, which lists all existent header values.
In case you're only interested in a particular parameter, you need to find
it's header name, e.g. "stla" & "stlo" for station latitude & longitude,
then it will print only these parameters.
Good luck, Eva

Could you give me the information How can I see the header of the file

Dear List,
I am using rdseed to extract SAC files from seed files:
rdseed -f x.seed -d -z 3 -b 2000000
This works fine, except for the Arrival Picks, they don't make it into
the sac header.
Picks are stored int he seed file and I can see them with:
rdseed -f x.seed -c
# Event phases:
B072F03 Station id: ABC
B072F06 Phase arrival time: 2005,003,19:32:59.0299
B072F10 Phase name: SG
I could read out this output…
