ASDF Sextant

Landing page for all things ASDF: https://seismic-data.org

This is Adaptable Seismic Data Format - if you are looking for the Advanced Scientific Data Format, go here: https://asdf.readthedocs.io/en/latest/

This is an experimental graphical user interface intended to enable the interactive exploration of ASDF files. It can mostly deal with earthquake event data sets and is currently not really suited to explore large noise data sets but we will add this capability in the near future.

Installation

Dependencies

The GUI as the following dependencies:

Python 2.7, 3.3, or 3.4
pyasdf
PyQt
pyqtgraph
qdarkstyle
pydot
graphviz (Not a Python package)

Same deal as always: If you know what you are doing install the dependencies in any way that works for you. Otherwise install the latest pyasdf version according to these instructions:

http://seismicdata.github.io/pyasdf/installation.html

and install the remaining dependencies with

$ conda install pyqt
$ pip install pyqtgraph qdarkstyle

Under Python 2, install pydot with

$ pip install pydot

pydot has no proper Python 3 packages, thus do

$ pip install https://github.com/nlhepler/pydot/archive/master.zip

graphviz

You furthermore need graphviz to view the provenance graphs. It is available for all systems and installation should be simple. Examples are:

$ sudo apt-get install graphviz  # Debian/Ubuntu
$ brew install graphviz          # OSX with Homebrew

Pyqtgraph Bug

There is a bug in the current version of pyqtgraph that shows an extra axis. Not a major issue but annoying. You can fix your local version by applying this patch:

https://github.com/pyqtgraph/pyqtgraph/commit/9df4df55c49ace05020e6b7c52128fdce09e2a8d

Alternatively you can just install pyqtgraph from the latest Github master.

GUI

It has no installer as of now - just clone it with git.

$ git clone https://github.com/SeismicData/asdf_sextant.git
$ cd asdf_sextant

Usage

Start it with

$ python main.py
