Dear Madam/Sir,
I have some problems in building SAC in cygwin. I have listed my
questions in order as follows:
1. I am using Windows and I installed "cygwin". However, I could not
open "aux" file in Windows and I tried to change its name as ",aux".
In "Makefile" files I replaced "aux" with ",aux", however I think that
I miss a point. How can i solve this "aux" problem?
2. My second question is ".dll" files are missed, how can I get them?
Sincerely yours

Hi guys,
I'm having troubles trying to merge a large number of noise files. I have SAC files of 1 hour each and I want to obtain first a file of a day and then a file of a week. It's the first time I'm using SAC, so my knowledge is limited. I'm trying to merge them however a message error keeps appearing:
ERROR 1801: Header field mismatch: Time Sampling [DELTA]: 0.002000 0.010000
Does anyone know how to fix this time sampling mismatch? All help is welcome!
Cheers!

Hello,
I believe I have correctly installed SAC on ubuntu and I have followed instructions from the README file and from this help forum for setting up the environment variables. However, when I try to run SAC I am not getting the SAC> prompt I expect. Instead I get the message "Total: x over 8 days", where x is some number that keeps increasing. How can I get SAC up and running correctly?
Thank you,
Dawson

Hello everyone,
So, I have a problema with my file.sac data, the thing is,
Because of my data have been a bad GPS time syncronization, every sample of
my file dosn't correspond with the real GPS time. But I have a time factor
correction to move every data to his real simple. I mean, for example in
the original file for the first simple correspond 01h03min33 seconds and i
have to rest one second to this simple (and the same operation to all the
seismogram)
How I have to apply this correction,…

Re: Correct the clock drift of a SAC file - George Helffrich - 2017-01-12 18:49:37
Hello,
I am new to SAC. I have unpacked the files but am still lost on what to do beyond that. I have read the read me file after unpacking and further action is still a bit ambiguous to me. Any advice is greatly appreciated. Maybe I can be pointed to a past thread on the SAC help forum.
Thank you,
Dawson Huth
