GMT Short Course for GSA 2017 Honolulu Meeting

Monday 22 May, 8:30 am-4:30 pm

Paul Wessel, Univ. of Hawai'i

UPDATE TWO

GMT 5.4.1 was released on May 9th, 2017. For the workshop we will use any GMT version from 5.4.1 and up, i.e., building from source via svn gives you what we call 5.5 (unreleased). We will work with various data sets during the short course and as a backup I will provide those locally using USB sticks in case Wi-Fi proves unsatisfactory.

This one-day workshop will introduce GMT to new users or reintroduce it to users with prior GMT experience. We will use GMT version 5 for this workshop. Participants must bring their own laptops and install GMT 5 prior to the start of the workshop. Detailed instructions for how to do this will be posted closer to the meeting (April) as we will want to use the latest version (we expect to release an update before the GSA meeting). If you cannot wait then follow our instructions on the GMT wiki called Building GMT from source.

GMT is normally used in a UNIX-like environment. Given the limited time we will focus on using GMT in the bash shell, but we will also demonstrate the new GMT/MATLAB toolbox. Users with prior experience with other UNIX shells, e.g., csh, tcsh, are welcome to use those shells but workshop instructions and examples will be tailored for bash.

There are four types of laptop setups that will be acceptable for this workshop:

• Apple MacBook of some sort: These run OS X which is UNIX-compliant. They need a UNIX package manager, and if you have never used one then we recommend MacPorts. You will also need to install XCode from the AppStore. The MacPorts site has detailed information and the steps depend on your version of OS X. If you already are using fink or HomeBrew then stick with what you know.
• Windows 10: You must be running a 64-bit version of Windows 10 Anniversary Update build 14393 or later. If not make sure you update your Windows version first. Our instructions will then allow you to enable the Windows Subsystem for Linux (Beta). An overview is given here .
• Windows 7 or earlier: I strongly recommend upgrading to Windows 10. If this is not an option then you will be using GMT within Cygwin. We have instructions for this on the GMT site but I will post more details in April. Oh, did I mention I strongly recommend upgrading to Windows 10?
• Linux (e.g., Windows/Linux dual-boot laptop): You should be good to go. Make sure to update to the latest patches.
