Good morning,
I tried converting seismic SAC data into SAF using Geopsy, but the results were not satisfactory. Is there any other way to do that conversion from SAC to SAF?
Thank you
Thank you for your reply,
It's a tabular file. I attached a file written using Seisan, i'm looking for other software or code that can convert sac files into a proper SAF files.
I tried to write manually the file, but i get some errors in the process using it as input for another program.
Redouane Chimouni If you did not get well code (dircet convert), I have alternate options to convert SAC to SAF. You can convert SAC to SEISAN format using 'wavetool' sub-routine program and . then convert Seisan format to SAF format using 'seisaf' sub-routine program. I have always convert like this. Seisan is the best free software, containing many sub-routines.
Dear, Thakur Prasad Kandel, thank you for your suggestion. But seisaf creates a flat signal for me every time.
Redouane Chimouni try it again original signal (without instrument correction) of SAC format. Instrument corrected signals may produces flat. I faced similar problem also.
Thakur Prasad Kandel I tried with mseed raw data with no conversion from SAC, and still get the flat signal. EW, NE and Z colomns, all = 0.0.
Redouane Chimouni please send me original waveform data. I will try it.
Thakur Prasad Kandel Thank you sir for your help, I couldn't attache the files here, I sent them on private message. I hope that's okay.
Redouane Chimouni Congratulations. you got success. I upload all related file in your private messanger.
Good morning.
Thank you Thakur Prasad Kandel and Fatih Bulut for your help.
The conversion was successful thanks to Thakur Prasad Kandel suggestion.
-For any further help for other users.
The SAF file contains 3 columns for the 3 components N, E and Z.
When converting only one component (Z for example) you'll get values only on the Z column in the SAF file and the other columns = 0. (That's why I got a flat signal).
1- It's best to convert "SAC" files into "mseed" (with messed2sac in my case).
2- Then merge the 3 components into one file with Seisan.
3- Now, when using "seisaf" the output will contain all 3 components.
i am using seisaf program to convert 1.man file of seisan in sAF format but it convert only one top station in saf format and not converting others...any one please healp me in this matter
