Python module for the Adaptable Seismic Data Format (ASDF).

Project description

Python module for the Adaptable Seismic Data Format (ASDF).

For further information and contact information please see these two web sites:


Version 0.7.5 (April 16, 2021)
* Fix an issue when appending waveforms of less than one second in length.

Version 0.7.4 (August 21, 2020)
* Workaround for an issue with HDF5 on PPC64.

Version 0.7.3 (July 22, 2020)
* Use a different way to copy the StationXML data in the process() function
  so it no longer gets stuck for large runs with MPI. See #62.

Version 0.7.2 (July 22, 2020)
* Replaced some numpy functionality that will be deprecated in future numpy
* Warnings will now raise when running the tests.

Version 0.7.1 (June 15, 2020)
* Write namespace abbreviations so that ObsPy can read the written
  StationXML files again with the other namespaces.

Version 0.7.0 (June 14, 2020)
* More conservative merging of stations. Stations are now only merged if
  everything except start and end date and the channels are the same.
  Otherwise they are not merged and will be retained. See #61. This might
  result in some slightly larger StationXML files in the ASDF files but
  should make no difference for downstream tools so it should affect

Version 0.6.1 (April 9, 2020)
* `pytest` is no longer a runtime dependency.

Version 0.6.0 (March 19, 2020)
* Drop support for Python <= 3.6.
* Fix a few deprecations warnings in Python >= 3.7.
* `flake8` and `pytest` no longer are runtime dependencies.
* Get rid of the special warnings handler as it interferes with other

Version 0.5.1 (September 24, 2019)
* Restore the ability to run tests with `python -m pyasdf.tests`.

Version 0.5.0 (September 24, 2019)
* Implement ASDF version 1.0.3 which allows a bit more flexibility
  regarding names of auxiliary data sets as well as provenance files.
* New .waveform_tags property for the dataset object return a set of all
  available waveform tags (see #46, #47)

Version 0.4.0 (March 12, 2018)
* Support for ASDF version 1.0.2. Allows writing traces that are less than
  one second short (see #44, #45).
* New get_waveform_attributes() method to quickly get all attributes
  for the waveforms of a stations (see #38, #39).

Version 0.3.0 (October 19, 2017)
* Support for ASDF 1.0.1 (the only difference to 1.0.0 is support for
  16 bit integer waveform data).

Version 0.2.1 (September 21, 2017)
* Don't attempt to write ASDF header info to files in read-only mode.
* get_coordinates() now works for StationXML files with a very large number
  of comments.
* Station.__getattr__() now works with underscores or dots as the network
  and station separator.
* __contains__() implemented for the station accessor object.

Version 0.2.0 (April 7, 2017)
* New script to convert a folder of SAC files to ASDF.

Version 0.1.4 (March 9, 2017)
* More visible warnings on Python 2 if necessary.

Version 0.1.3 (March 8, 2017)
* Now also works with Python 3 under windows.

Version 0.1.2 (March 7, 2017)
* Also shipping license file.

Version 0.1.1 (March 7, 2017)
* Stable, tagged version.
