Pyrocko I/O Modules

Input and output of seismic traces.

This module provides a simple unified interface to load and save traces to a few different file formats. The data model used for the pyrocko.trace.Trace objects in Pyrocko is most closely matched by the Mini-SEED file format. However, a difference is, that Mini-SEED limits the length of the network, station, location, and channel codes to 2, 5, 2, and 3 characters, respectively.

Metadata IO

• pyrocko.io.quakeml parses QuakeML (https://quake.ethz.ch/quakeml/) into a pyrocko data model.
• pyrocko.io.stationxml represents a FDSN stationXML model.

.. rubric:: Notes

.. [#f1] For SAC files, the endianness is guessed. Additional header information is stored in the Trace's meta attribute. .. [#f2] Seisan waveform files can be in little (seisan.l) or big endian (seisan.b) format. seisan currently is an alias for seisan.l. .. [#f3] The KAN file format has only been seen once by the author, and support for it may be removed again. .. [#f4] YAFF is an in-house, experimental file format, which should not be released into the wild. .. [#f5] ASCII tables with two columns (time and amplitude) are output - meta information will be lost.
