 Hello, this is Lee.  I want to build my own SAC read-write program. Like a Guralp guys did.  But I can't find information about detailed SAC file format structure.  I want more detailed structure information. Like SEED manual.  Do you have a SAC file format structure manual? Or something detailed description?  If not, can you tell me how guralp guys did it?(I mean, SCREAM! program..It can export data in SAC format.)  Thank you.  Lee.

Hi Alessandro, You need a later version of sac. In Mac OSX 10.6 some systems calls were changed that were needed for the version of evalresp embedded in your sac. Evalresp has been fixed to work in 10.6 and the fixes are included in later versions of sac. regards, Chad wrote: >I use binary sac 101.2 OSX on my MacBook Pro (10.5.8, Intel core 2 >duo) and have no problem with "transfer from evalresp", while the same >code gives this error > > >WARNING: evresp_; n… [more]

Hello! I need help to do traces stacking with SAC. For the start: 1) I have preprocessed (bandpass filtered) waveforms where I added to the header time of the first arrival. 2) I need to clip these files (10 sec before and 10 after the first arrival ) and align them. 3) I need to stack these traces. 1) and 3) - is not a problem. I am not sure how to handle 2). I also would like to plot all these clipped traces on one plot. Thank you.

I created an alphanumeric SAC file with the SAC software (v.101.4) (using the commands FUNCGEN and WRITE ALPHA) and was wondering about the first string header line (fields KSTNM & KEVNM, 8+16 chars) which seems to be one character longer (25) than stated by the manual, see attached screenshot "sac_alpha.png". I then manually filled this line with a test value of "012345670123456789ABCDEFG" and read it in with the SAC software again. It states the KEVNM header as "012345679ABCDEFG", see attach… [more]
