Real-time trace view.


scrttv visualizes real-time waveform data (see scrttv overview) of a defined window length (default=30 minutes) and of defined streams/stations (default is primary station channels). scrttv switches between two modi. In the normal mode the trace order is given by the configuration file. In the event mode the traces are sorted by epicentral distance to the latest origin received from the messaging. Additional to the waveform traces information about gaps, picks and the time of incoming origins are displayed.


scrttv overview

An example of scrttv and the dialog window to set preliminary origin. Tab 1-2 = enable/disable tab; Counts = maximum counts of a stream; Info = stream information (station, network and channel code); Filter = filter status of the traces; Status = connection status.

scrttv shows two tabs: the enabled and the disabled tab (see scrttv overview: Tab 1-2). Stations listed in the disabled tab are excluded from processing (e.g. picking). To move a station from one tab to another just drag and drop the trace to the new tab. An alternative solution is to double click on the trace label to disable a trace.

Normally, the raw data are displayed. Pressing f the predefined bandpass filter of third order from 0.5 Hz to 8 Hz, BW(3,0.5,8) is applied to the traces. Also zoom functions for the time and amplitude axis are provided.


Artifical origin.

In case the operator recognizes several seismic signals, an artificial/preliminary origin can be set by either pressing the middle mouse button on a trace or by opening the context menu (right mouse button) on a trace and selecting “Create artificial origin”. The following pop-up window shows the coordinates of the station and the time the click was made on the trace. Both are used to generate the new artificial origin without any arrivals. Pressing “Create” sends this origin to the LOCATION group. This artificial origin is received e.g. by scolv and enables an immediate manual analysis of the closest traces.

Among the configurable parameters are:

  • Global bindings:

  • Module configuration:

    • network, stations, locations and streams to show extending or overriding the default definition (,

    • data filters,

    • buffer size controlling the lenght of loaded data (bufferSize),

    • sorting of traces upon arrival of new origins (resortAutomatically),

    • reference coordinate for sorting traces by default (streams.sort.*),

    • region filters (streams.region.*),

    • grouping of streams with different properties,

    • number of traces to show with fixed height (streams.rows).

  • Scheme parameters in global module configuration:

    • trace properties and trace background colors,

    • font and general GUI parameters.

More parameters are available on the command-line:

scrttv -h

Enable / Disable Stations

To enable or disable a station for automatic data processing in SeisComP select a station code with the mouse and drag the stations to the disable / enable tab or simply double-click on the station code.

Stream Filtering

scrttv allows filtering of waveforms. The hotkey f can be used to toggle the list of filters pre-defined in filter or in filters. Note that the list of filters defined in filters overwrites filter. Activate autoApplyFilter to filter all traces at start-up of scrttv with the first filter defined in filters. The applied filter is shown in the lower left corner (see Figure below). To show filtered and raw data together use the hotkey r.

Stream Grouping

scrttv allows grouping of stations and even streams with different properties, e.g. colors or color gradients.


Stations with 2 groups and different line color gradients. Ungrouped stations are visible with default line properties. The applied filter is shown in the lower left corner. The tooltip on top of station CX.PB19 is derived from$name.title.


Adjust the scrttv module configuration (scrttv.cfg).

  1. Define the groups:

    • add a new group profile to

    • set the properties for this group profile. Colors and color gradients are defined by hexadecimal values or by color keyword names. When choosing gradients the colors of the traces within one group will be varied in alphabetic order of the streams.

    • set a group title in$name.title.

  2. Register the groups in streams.groups.

Viewing groups

  1. Open scrttv to view the data.

  2. Select Sort by group in the Interaction menu or use the hotkey 5 to sort the traces by their groups.

  3. Mouse over a station belonging to a group. The tooltips shows the group title.

  4. For maintaining the sorting by groups adjust the scrttv module configuration (scrttv.cfg):

    resortAutomatically = false

Record Borders

The borders of records are toggled by using the hotkey b.


Record borders in box mode on top of waveforms.

Border properties can be adjusted and signed records can be visualized by colors configured in the scheme parameters in global.cfg or scrttv.cfg:

  • scheme.records.borders.drawMode: Define where to draw borders, e.g. on top, bottom or as boxes.

  • scheme.colors.records.borders.*: Define pen and brush properties.

Offline Mode

To start scrttv without connection to the messaging use the option –offline or simply provide the miniSEED data file, e.g.:

scrttv [your miniSEED file]

In offline mode event parameters given in SCML files, e.g. from offline processing, can be loaded using the File menu.

scrttv inherits global options.


Type: int

Unit: s

If greater than 0 then all traces for which the data latency is higher than this value are hidden. Default is 0.


Type: boolean

If enabled then all traces are sorted by distance when a new origin arrives. Default is true.


Type: boolean

If enabled, picks are shown. Default is true.


Type: string

Defines the filter to be used when filtering is activated. This is only being used if filters is not set otherwise it is overridden. This option is mainly for backward compatibility. Default is BW(3, 0.5, 8.0).


Type: list:string

Defines a list of filters that is cycles through when pressing ‘f’. This options supersedes the filter option. If not defined then filter is used instead. If defined then this filter list is used exclusively and the filter option is ignored.


Type: boolean

Activates the first filter of the configured filter list after startup. This is equivalent to pressing ‘f’. Default is false.


Type: int

Unit: s

Defines the buffer size in seconds of the ring bu of each trace. Default is 1800.


Type: boolean

If set to true all traces will be visible on application startup independent of data availability. Default is false.


Type: int

Unit: s

Time span in seconds to switch back to the last view after an origin caused resorting. The default is 15min. Default is 900.

Type: list:string

Defines a list of channels codes to be displayed. List items may contain wildcards at any position and are separated by comma. The list is intersected with all channels configured in inventory.


default : display all streams configured by global bindings

Type: list:string

If not empty then all stream patterns are part of the blacklist. The blacklist is only active if "" is omitted and the default stream list according to the bindings is to be shown. Each pattern can include wildcards (either ? or *). The pattern is checked against the channel id which is a concatenation of network code, station code, location code and channel code separated with a dot, e.g. "GE.MORC..BHZ".


Type: integer

Number of rows to show at once in one windows. If more traces than rows are loaded, the are accessible by a scroll bar.


Type: string

Stream group profiles to be considered. Use comma separation for a list of groups.


streams.sort.* Configures the initial stream sorting.


Type: string

The sort mode applied initially. Allowed values are: config, distance, station, network, group. Default is distance.


Type: double

Unit: deg

Latitude of the initial location for sorting traces. Only valid if mode == distance. Default is 0.0.

Type: string

Title of the group visible as a tooltip of the traces.

Note$name.pen.* Defines the trace pen of the group.\$name.pen.color

Type: color

The color of the pen. If not given, the default trace color is being used. The parameter is overridden by "$profile.gradient" .\$name.pen.gradient
