Thread: Re: PROBLEM WITH SPECTROGRAM IN SAC 32 BITS

Silvana,

Can you let me know what version of sac you are using and what operating system you are running ?

Thanks,
Brian

Silvana,

Checking old e-mails of the sac-help, i find an e-mail from Brian Savage (Set,15 2009)
where him suggest the update of sac software to avoid the X problem.

Cheers,

or at best case, only sac opened the window but do not plot the spectrogram

Silvana,

The file 2005.102.03.46.00.0000.XJ.HUDS..HHN.D.SAC is only 300 seconds
long, and has a high-frequency component. I would suggest reducing the
values of window and slice in the spectrogram command, and increasing
ymax.

Also if you cut around the event then it looks better!

qdp off
cut 50 80
r 2005.102.03.46.00.0000.XJ.HUDS..HHN.D.SAC
rmean
rtr
taper
spectrogram window 2 slice 0.2 method mem order 400 ymin 0 ymax 20 cbar

Hello:
I need plot a spectrogram, but this script only work in SAC 64 bits

SAC> rtr
SAC> taper
SAC> interpolate delta 0.2
SAC> spectrogram window 200 slice 50 method mem order 400 ymin 0.0 ymax

in 32 bits the error is

Window size: 999 Overlap: 749 FFT size: 2048
Spectrogram dimensions are 512 by 3 .
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 72 (X_PutImage)
