Introduction

SeisBase is a framework for working with univariate geophysical data on 64-bit systems. SeisBase is designed around three basic principles:

  • Ease of use: one shouldn't need a PhD to understand command syntax.
  • 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

SeisBase stores data in minimalist containers that track the bare necessities for analysis. New data are easily added with basic operators like +. Unwanted channels can be removed just as easily. Data can be written to a number of file formats.

Installation

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

pkg> add SeisBase; build; precompile

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

pkg> test SeisBase

and allow 10-20 minutes for tests to complete. Exit the Pkg environment by pressing Backspace or Control + C.

Getting Started

At the Julia prompt, type

using SeisBase

You'll need to repeat this step whenever you restart Julia, as with any command-line interpreter (CLI) language.

Learning SeisBase

An interactive tutorial using Jupyter notebooks in a web browser can be accessed from the Julia prompt with these commands:

julia> p = pathof(SeisBase);

julia> d = dirname(realpath(p));

julia> cd(d);

julia> include("../tutorial/install.jl");

SeisBase also has an online tutorial guide<tutorial>, intended as a gentle introduction for people less familiar with the Julia language. The two are intentionally redundant; Jupyter isn't compatible with all systems and browsers.

  • Reading Data<readdata>: learn how to read data from file
  • Web Requests<getdata>: learn how to download data

Updating

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