Re: [MSNoise] Some little things and one question about data from more than one network.

by Kasper van Wijk

Tom, as you suggested, the problem may be bigger than file names/ networks. Here's the output after changing to the NZ network name of our extra station to match that of the rest of the stations. Both are mseed data types: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/site-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 540, in runfile execfile(filename, namespace) File "/home/devora/Test/s03compute_cc.py", line 214, in <module> stream.merge(fill_value=0) File "/usr/lib64/python2.7/site-packages/obspy/core/stream.py", line 1715, in merge self._mergeChecks() File "/usr/lib64/python2.7/site-packages/obspy/core/stream.py", line 1660, in _mergeChecks raise Exception(msg) Exception: Can't merge traces with same ids but differing data types!

Dear all, Someone can explain me in which way I can populate in the configurator the filters tab?? When I try to start cross correlation give me this error message: 'NO FILTERS DEFINED, exiting'. what it means? thank you very much and I hope to find a solution as soon as possible. cheers, Carmelo The University of Aberdeen is a charity registered in Scotland, No SC013683.

Some little things and one question about data from more than one network.

by Kasper van Wijk

Dear Tom et al., I am working with a student to replicate the install of MSNOISE for the Auckland Volcanic Field. Below are a few things we have ran into: 1. http://msnoise.org/doc/workflow.html#module-MSNoise.s001configurator misses the explicit call to start the configurator: python s001configurator.py (this is obvious to anyone who has used MSNOISE before, but stumped the aforementioned new student) 2. On CENTOS linux, I have an issue with sqlalchemy. The "fix" is as ugly as it is mysterious: http://stackoverflow.com/questions/14600530/cant-import-from-sqlalchemy-ext… 3. We have a font problem (which I don't know how to fix), but starting the configurator, we get the attached warning. Just a warning, though. 4. Is it correct that sqlite can only work on one thread? [devora@localhost MSNoise-master]$ python s01scan_archive.py --init -t 2 2014-08-22 10:14:13,724 [INFO] *** Starting: Scan Archive *** 2014-08-22 10:14:13,727 [INFO] Initializing (should be run only once) 2014-08-22 10:14:13,727 [INFO] You can not work on 2 threads because SQLite only supports 1 connection at a time 2014-08-22 10:14:13,727 [INFO] Will work on 1 threads 5. And this is where are currently: we imported a station into our NZ network with a different network name. This resulted in errors when pairing the AK station with an NZ station. What should we do? After getting an error, we tried renaming the AK data to NZ to be consistent, but we are unable to cleanly perge the AK info in the database. Alternatively, can we set up two networks in the configurator? Cheers, kasper

MSNoise releases - Development

by Thomas Lecocq

Dear MSNoise users, You might have noticed I am working on the codes, and updating the "branches" of the GitHub repository. I just wanted to remind you all that, except if you're really reckless, you should only use "Releases" versions of the code. The releases are available here : https://github.com/ROBelgium/MSNoise/releases to be sure, always download the "Lastest" : https://github.com/ROBelgium/MSNoise/releases/latest The branches (tests, msnoise-admin, etc) and the 'master' branch are often updated with code that is not yet fully tested or complete, and so could not work. I have started writing unit tests for the code, so, in a near future, one could just look at the "Build Status" of TravisCI (CI stands for Continuous Integration) to check if all is OK to test the "master" instead of "Releases" ! Best regards from Brussels Thomas ps: as always, if you use MSNoise, please let me/us know! Certainly if you had/have problems ! If you think something would be useful for others, submit ideas/issues/suggestions to the https://github.com/ROBelgium/MSNoise/issues ! -- Dr. Thomas Lecocq Geologist Seismology - Gravimetry Royal Observatory of Belgium * * * * * * * * * * --------- http://www.seismology.be http://twitter.com/#!/Seismologie_be
