miniseed and tankplayer

[gonzalo antonio fernandez marañon]

Dear all.

Hope you are enjoying the earthworm world like me.

I have some doubts about my digitizer and tankplayer module.

I have a digitizer eentec that sends me miniseed filse (steim2) each
10 minutes, I would like to use tankplayer to get the data into
earthworm format, but I cant beacuse I need to conver the miniseed
files into a tank format, I found here in a previuos forum that Billy
got the nq2ring, I downloaded it but I can bot get th .exe file, so I
when I start my earthworm the process ID told me -NoExe (it means that
there is no nq2ring.exe), (We are working in a windows server), Do
you know where can I get the nq2ring.exe???
Or do you know another way to convert miniseed files into earthworm
messages (TB2)???

my miniseed file is like this:

12971520.BHN

Station:DS1

Thanks for helping us.
Best Regards.

Hi Gonzalo,

nq2ring is a UNIX system only program since it was written  using the UCB qlib2, so you cannot get it to
work on Windows without considerable rewriting of the program.

Alternatively you can write a script that uses ms2tank that uses libmseed to convert your mseed files to tank format and play them with tankplayer using the GetFromDir feature.

OR

you can formulate the files into the appropriate directory structure that Ruben's mseedarchplayer uses and that will work.

Cheers,

Paul

Hi everybody,

I'm on the way to upgrade our EarthWorms installations from 7.3 or 7.4 to 7.5, using latest SVN release (maybe not a very idea) and I just ran into a problem with the last localmag update (version 2.1.8).

I'm using localmag in a command line mode, embedded within hyp71_mgr with this kind of shell line : "localmag localmag.d < hyp2000_arc_message".
Until 2.1.6 release, there where no problems (I think this is the one included within 7.5). But with 2.1.8, localmag doesn't seem to be able to parse the hyp2000_arc_message.
It gives me this errors in the log file :
" procArc: error reading arc shadow line:

procArc: error reading arc message (1 lines and 0 phases)." .

I didn't change anything in the configuration, except that I updated the localmag.d file to reflect the changes I found in src/seismic_processing/localmag/localmag.d file (all the differences are commented or not used).

Did you notice anything about this ?
Is there any reason for this change in behaviour between 2.1.6 and 2.1.8 ?
I ran the memphis test and there was no error when localmag is used as a module, but there is the same error if I use it within hyp71_mgr.

Hi Jean-Marie,

I don't have any ideas why this shouldn't work.

Do this test if you have time to see what is going on:

1. take the memphis test and store the .arc file using ew2file

2. then run localmag from svn in command line mode like you are trying to with
the localmag.d modified to reflect that you are sending the file in via stdin.

If that works, then there is a problem with the .arc file . You could also test
against an older version to make sure it is not the .arc input file.

If it is not the .arc file, please open a ticket on this one. We will make sure
that trac is working for ticketing shortly.

Also, in future, if you are dealing with an SVN version, please contact the ewdev
group first before firing it out to the EW community at large since it was the
developers that probably did something unusual with the code :).

Cheers,

Paul

Jean-Marie,
hypoinverse produces an arc message with a series of couple of lines: the main line and its shadow.
Actually, when I rewrote the function procArc() in order to read also the phase lines, I took for granted this format.
Could you provide your arc message? I will have a look also in the hypo-manual ;-)

I just does that test, and unfortunately, the problem is still the same.
I attach the arc file used for this test (suffix 003) and the one from hyp71_mgr (suffix 002).
Both are producing the same error.

Sure, sorry for the mistake ;) .
