Dear Mei,
revise your first line as follows,
setbb log '&1,kstnm& .split'
As per the second line with an evaluation, there may be a issue. I tried to
recreate the following example given on p.49 in SAC Primer and came across
a similar problem. Perhaps SAC developers can provide an explanation.
SAC Primer Example
----------------------------
SAC> setbb x 1 ;* set x to 1
SAC> message "sqrt (%x% + %x%) is (sqrt (%x% + %x%))"
sqrt 2.000000 is 1.41421
My result on SAC 101.6

Hello,
I am attempting to run a script that needs to set the blackboard variable for the beginning and end of both the east and north components of my files. The macro setup that I’m using is:
foreach sta (`cat stationList`)
sac << EOF

The error that results is :

I am wondering if anyone can help me with the following problem:
After I installed the latest version of SAC (101.6 for X86-64) I found that
a piece of my SAC macro codes didn't work and which worked and still works
well in the older version of SAC (101.3b for X86-64). The piece of codes
and their corresponding output the two versions of SAC are as the following:
101.3b version:
setbb log " ( concatennate &1,kstnm& .split ) "
message "%log%"
HY16.split
101.6a version:
setbb log " ( concate…

Hello,
I run band pass filter using command as:
bp co 0.01 0.1 n 4 p 2
the original waveform is the top one (with dt=1.0s, npts=7200), the filtered one is at the bottom, why there is a strange wiggle in the left edge?

Matteo Bagagli
Hello to all,
I'm new to the mailing list, I'm a researcher from Pisa.
Now my question in basically simple, but I don't think the answer will be
the same.
As I pointed out in the mail-object, I was wondering how I could get the
FINAL date
of the time series I've read in SAC 101.6a??
To make it clearer, if I use the "ppk" function and click over the last
sample of the plot
it appears on screen the relative date: how can I export that date from
SAC?
In the header I could get only the START DATE …

Hello,
I was wondering if anyone could help me with writing a SAC macro that reads in multiple event files, and deletes any events that are beyond a certain epicentral distance away from the station.
I have events with epicentral distances from 30-90 degrees; however, I want to kick out any events with epicentral distances greater than 85 degrees.
Is there a way in SAC to kick out those events from 85-90 degrees that I don’t want?
I have checked the SAC header files, and the DIST functions…
