Thread: taup_setsac errors in setting theoretical arrival times of phases

As noted in the traveltime help file that comes with version 101.4,
traveltime in IRIS/SAC does not work. although not directly related to
your quesiton, I would appreciate it if anyone has succeeded in getting
something like the iaspei-tau program ttimes working in C. If so, please
send me the source as I would like to fix at least that part of the
sss/traveltime command.

What you have done is very similar to what is suggested in the SAC help
file http://www.iris.edu/software/sac/commands/sss.com/traveltime.html
escept you leave out the sc and the -1 in P-1. On my mac (OS 10.6) I
reproduced the results in the help file with a line like yours:

SAC> taup_setsac -evdpkm -ph P -verbose test.z
test.z
Using gcarc: 3.3574646
test.z searching for P
P: P END
0 1 2 3 4 5 5 4 3 2 1 0
minRayParam=254.33137581441554 maxRayParam=1098.448275862069
minDistance=0.0 maxDistance=98.39983407057541
-----------------
test.z 5 arrivals found.
test.z phase found P -> t0, travel time=64.63958
test.z phase found P -> t0, travel time=64.35809
test.z phase found P -> t0, travel time=60.571896
test.z phase found P -> t0, travel time=60.38368
test.z phase found P -> t0, travel time=53.694054
SAC> r test.z
SAC> lh amarker t1marker

FILE: test.z - 1
------------

amarker = 10.47 t1marker = 10.494 (P)

As you get the same error outside of SAC, it sounds like your immediate
problem is with the taup on your system.

Dear Friends and Colleagues:

In an attempt to put the theoretical arrival times in SAC headers, I
have used a program contained in TAU_P package, called "taup_setsac".  I
called this program both within and without SAC environment but I always
get the following error:

SAC> taup_setsac -ph P -evdpkm -verbose GRA1.Z
Exception in thread "main" java.lang.NullPointerException
at edu.sc.seis.TauP.TauP_SetSac.parseCmdLineArgs(TauP_SetSac.java:353)
at edu.sc.seis.TauP.TauP_SetSac.main(TauP_SetSac.java:382)

Does anyone know what goes wrong? Or are there alternative ways to do
the job?

I have SAC 101.4 running on Fedora14 with Java SE  build 1.6.0_25-b06.
The other TAUP programs run without any error.

Thank you in advance for your hints.

Hi

What version of TauP are you using?

I think this bug has been fixed in the beta version, 2.0beta9
available at http://www.seis.sc.edu/taup/
and so you might want to try that if you still have problems.
