.. highlight:: rst .. _scevtstreams: ############ scevtstreams ############ **Extract stream information with time windows from picks of an event.** Description =========== scevtstreams reads all picks of an event and determines the time window between the first pick and the last pick. In addition a symmetric or an asymmetric time margin is added to this time window. It writes the streams that are picked including the determined time window for the event to stdout. This tool gives appropriate input information for :ref:`scart`, :ref:`fdsnws` and :cite:t:`capstool` for :cite:t:`caps` server (Common Acquisition Protocol Server by gempa GmbH) to dump waveforms from archives based on event data. Output Format ============= The generated list contains start and end time as well as stream information. Generic: .. code-block:: properties starttime;endtime;stream Example: .. code-block:: properties 2019-07-17 02:00:00;2019-07-17 02:10:00;GR.CLL..BHZ Examples ======== #. Get the time windows for an event in the database: .. code-block:: sh scevtstreams -E gfz2012abcd -d mysql://sysop:sysop@localhost/seiscomp #. Get the asymmetric time windows for an event in an XML file. The time window starts 120 s before the first pick and ends 500 s after the last pick: .. code-block:: sh scevtstreams -E gfz2012abcd -i event.xml -m 120,500 #. Create a playback of an event with a time window of 5 minutes data and sort the records by end time: .. code-block:: sh scevtstreams -E gfz2012abcd -d mysql://sysop:sysop@localhost/seiscomp -m 300 |\ scart -dsvE --list - ~/seiscomp/acquisition/archive > gfz2012abcd-sorted.mseed #. Download waveforms from Arclink and import into local archive. Include all stations from the contributing networks: .. code-block:: sh scevtstreams -E gfz2012abcd -d mysql://sysop:sysop@localhost/seiscomp -m 300 -R --all-stations |\ scart --list - ./my-archive #. Create lists compatible with :ref:`fdsnws` or `caps `_: :: scevtstreams -E gfz2012abcd -i event.xml -m 120,500 --fdsnws scevtstreams -E gfz2012abcd -i event.xml -m 120,500 --caps .. _scevtstreams_configuration: Module Configuration ==================== | :file:`etc/defaults/global.cfg` | :file:`etc/defaults/scevtstreams.cfg` | :file:`etc/global.cfg` | :file:`etc/scevtstreams.cfg` | :file:`~/.seiscomp/global.cfg` | :file:`~/.seiscomp/scevtstreams.cfg` scevtstreams inherits :ref:`global options`. Command-Line Options ==================== .. program:: scevtstreams :program:`scevtstreams [options]` Generic ------- .. option:: -h, --help Show help message. .. option:: -V, --version Show version information. .. option:: --config-file arg Use alternative configuration file. When this option is used the loading of all stages is disabled. Only the given configuration file is parsed and used. To use another name for the configuration create a symbolic link of the application or copy it. Example: scautopick \-> scautopick2. .. option:: --plugins arg Load given plugins. .. option:: -D, --daemon Run as daemon. This means the application will fork itself and doesn't need to be started with \&. .. option:: --auto-shutdown arg Enable\/disable self\-shutdown because a master module shutdown. This only works when messaging is enabled and the master module sends a shutdown message \(enabled with \-\-start\-stop\-msg for the master module\). .. option:: --shutdown-master-module arg Set the name of the master\-module used for auto\-shutdown. This is the application name of the module actually started. If symlinks are used, then it is the name of the symlinked application. .. option:: --shutdown-master-username arg Set the name of the master\-username of the messaging used for auto\-shutdown. If \"shutdown\-master\-module\" is given as well, this parameter is ignored. Verbosity --------- .. option:: --verbosity arg Verbosity level [0..4]. 0:quiet, 1:error, 2:warning, 3:info, 4:debug. .. option:: -v, --v Increase verbosity level \(may be repeated, eg. \-vv\). .. option:: -q, --quiet Quiet mode: no logging output. .. option:: --component arg Limit the logging to a certain component. This option can be given more than once. .. option:: -s, --syslog Use syslog logging backend. The output usually goes to \/var\/lib\/messages. .. option:: -l, --lockfile arg Path to lock file. .. option:: --console arg Send log output to stdout. .. option:: --debug Execute in debug mode. Equivalent to \-\-verbosity\=4 \-\-console\=1 . .. option:: --log-file arg Use alternative log file. Database -------- .. option:: --db-driver-list List all supported database drivers. .. option:: -d, --database arg The database connection string, format: service:\/\/user:pwd\@host\/database. \"service\" is the name of the database driver which can be queried with \"\-\-db\-driver\-list\". .. option:: --config-module arg The config module to use. .. option:: --inventory-db arg Load the inventory from the given database or file, format: [service:\/\/]location . .. option:: --db-disable Do not use the database at all Input ----- .. option:: -i, --input arg Input XML file name. Reads event from the XML file instead of database. Use '\-' to read from stdin. .. option:: -f, --format arg Input format to use \(xml [default], zxml \(zipped xml\), binary\). Only relevant with \-i. Dump ---- .. option:: -E, --event arg The ID of the event to consider. .. option:: --net-sta arg Filter read picks by network code or network and station code. Format: NET or NET.STA .. option:: --nslc arg Stream list file to be used for filtering read picks by stream code. '\-\-net\-sta' will be ignored. One line per stream. Line format: NET.STA.LOC.CHA. Output ------ .. option:: -m, --margin arg Time margin around the picked time window, default is 300. Added before the first and after the last pick, respectively. Use 2 comma\-separted values \(before,after\) for asymmetric margins. Example: 120,300. .. option:: -S, --streams arg Comma separated list of streams per station to add. Example: BH,SH,HH. .. option:: -C, --all-components arg Specify whether to use all components \(1\) or just the picked ones \(0\). Default: 1. .. option:: -L, --all-locations arg Specify whether to use all location codes \(1\) or just the picked ones \(0\). Default: 1. .. option:: --all-stations Dump all stations from the same network. If unused, just stations with picks are dumped. .. option:: --all-networks Dump all networks. If unused, just networks with picks are dumped. This option implies \-\-all\-stations, \-\-all\-locations, \-\-all\-streams, \-\-all\-components and will only provide the time window. .. option:: -R, --resolve-wildcards flag If all components are used, use inventory to resolve stream components instead of using '?' \(important when Arclink should be used\). .. option:: --caps Dump in capstool format \(Common Acquisition Protocol Server by gempa GmbH\). .. option:: --fdsnws flag Dump in FDSN dataselect webservice POST format.
