YAML based file formats in Pyrocko¶
The default IO format for many of Pyrocko’s internal structures and its
configuration files is the YAML format. A generic
mechanism is provided to allow users to define arbitrary new types with YAML IO
support. These can nest or extend Pyrocko’s predefined types. The functionality
for this is provided via the
pyrocko.guts module, usage examples can
be found in section Working with the guts package.
For example, here is how a
pyrocko.model.Station object is
represented in YAML format:
--- !pf.Station network: DK station: BSD location: '' lat: 55.1139 lon: 14.9147 elevation: 88.0 depth: 0.0 name: Bornholm Skovbrynet, Denmark channels: - !pf.Channel name: BHE azimuth: 90.0 dip: 0.0 gain: 1.0 - !pf.Channel name: BHN azimuth: 0.0 dip: 0.0 gain: 1.0 - !pf.Channel name: BHZ azimuth: 0.0 dip: -90.0 gain: 1.0
Though YAML or standard file formats can be used to hold station or event information, for the sake of simplicity, two basic text file formats are supported for stations and events. One other simple file format has been defined to store markers from the Snuffler application. These file formats are briefly described in the following sections.
