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.

  • 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)
    SAC>

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

  • 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.
