Introduction

SeisIO is a framework for working with univariate geophysical data. SeisIO is designed around three basic principles:

  • Ease of use: you shouldn’t need a PhD to study geophysical data.
  • Fluidity: working with data shouldn’t feel clumsy.
  • Performance: speed and efficient memory usage matter.

The project is home to an expanding set of web clients, file format readers, and analysis utilities.

Overview

SeisIO stores data in minimalist containers that track the bare necessities for analysis. New data are easily added with basic commands like +. Unwanted channels can be removed just as easily. Data can be saved to a native SeisIO format or written to other supported file formats.

Installation

From the Julia prompt: press ] to enter the Pkg environment, then type

add SeisIO; build; precompile

Dependencies should install automatically. To verify that everything works correctly, type

test SeisIO

and allow 10-20 minutes for tests to complete. To get started, exit the Pkg environment by pressing Backspace or Control + C, then type

using SeisIO

at the Julia prompt. You’ll need to repeat that last step whenever you restart Julia, as with any command-line interpreter (CLI) language.

Getting Started

The tutorial is designed as a gentle introduction for people less familiar with the Julia language. If you already have some familiarity with Julia, you probably want to start with one of the following topics:

Updating

From the Julia prompt: press ] to enter the Pkg environment, then type update. Once updates finish, restart Julia to use them.

Getting Help

In addition to these documents, a number of help documents can be called at the Julia prompt. These commands are a useful starting point:

?chanspec           # how to specify channels in web requests
?get_data           # how to download data
?read_data          # how to read data from file
?timespec           # how to specify times in web requests and data processing
?seed_support       # how much of the SEED data standard is supported?
?seis_www           # list strings for data sources in web requests
?SeisData           # information about SeisIO data types
?SeisIO.KW          # SeisIO shared keywords and their meanings
