Greetings, Do anybody know how to convert a sac file into ascii format. I'm doing a thesis research in cross-correlation of seismic noise , and I want to use several inputs in ascii, while my noise data are in sac format. Can anyone help me?

Hi, I used to use SAC in UNIX, but currently I have SAC for Mac OS. I would like to read the files in SAC format but I don't know how to byteswap files. Thanks.

Dear SAC users, I am trying to get ps images in my script but all plots become rotated by -90 degrees at the end: SAC>r 2009010129/* SAC>p1 --> plots 6 stations where t=0 is on the LEFT SAC>SGF PREFIX data NUMBER 1 DIRECTORY /home/test/data SIZE NORMAL SAC>bd sgf; p1; ed sgf SAC>sgftops data001.sgf data001.ps >gv data001.ps --> plots 6 stations where t=0 is on the BOTTOM Why this rotation is happenig? Is this normal? How do I rotate it back? My version: SEISMIC ANALYSIS CODE [01/29/200… [more]
Hi, Certainly, the LLNL/IRIS distribution of SAC can read SAC files in either endian. I was trying to read a bad data set and for that reason SAC couldn't recognize my SAC files. Now, I'm using good data and I don't have to byteswap the file to read it with SAC in Mac. Thank you very much.. -- ________________________________________________________________ Claudia Quinteros Ingeniera Geofísica FUNVISIS - Fundación Venezolana de Inve… [more]
Inspired by the recent discussion about TRANSFER on this list, I am putting in the following paragraph in the TRANSFER HELP file: Care must be taken when calling TRANSFER a second time within a single SAC session, because in the second call TRANSFER will use the same arguments for FROM, TO, FREQ, etc. as in the first call unless an alternative argument is explicitly provided. Comments?

Hi I have a problem with transfer command in Sac. I have removed an instrument response and applied Wood Anderson to a wave in two different ways but I saw some problems. First, I removed SS1 response with: transfer from polezero subtype $resp freq 1 10, then I applied WA response with this command: transfer to WA Furthermore, I did both with this command: transfer from polezero subtype $resp to WA freq 1 10 >From the above you might got idea that the result should be similar, but the resul… [more]
