# Code and data management with Git

This is the website for the course *Code and data management with Git*. This
course consists of an introduction to working with the
[Git](http://git-scm.com/) version control system for data analysis and is
aimed primarily at researchers in the LUMC.

The Git system is widely used by software developers, but can also be used for
project management. In the LUMC we use [GitLab](https://git.lumc.nl) as a
collaborative environment on top of Git. By keeping track of all versions,
history, etc, GitLab makes your projects more reproducible and collaboration
with colleagues easy ([introduction](http://doc.gitlab.com/ce/gitlab-basics/README.html)).

This year the contents will be slightly less advanced on the technical side
(no branching, no git-annex). Instead, there is more focus on using the LUMC
GitLab server and using Git for data analysis projects.

## Prerequisites

Affinity with the UNIX shell is required before taking the course. For
example, our
[scripting course](https://humgenprojects.lumc.nl/trac/humgenprojects/wiki/scripting)
is more than enough, or you could go though
[tutorials 1-3 here](http://www.ee.surrey.ac.uk/Teaching/Unix/).

We encourage you to bring your own laptop, but make sure it has a terminal and
[Git](http://git-scm.com/) installed. We work with
[Linux](http://en.wikipedia.org/wiki/Linux), but Git also runs on Mac OSX.
Windows is not ideal, but here are [some suggestions](WINDOWS.md).

We can also provide you with a laptop that has all the required software
installed. The lessons are interactive, meaning that you really need a
laptop.

## Using the course materials

There is one [Git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules)
on which this repository depends:

- **[presentation](https://git.lumc.nl/j.f.j.laros/presentation)** template for
  presentations in LaTeX.

First clone this repository, then fetch the data from the submodule:

    git clone https://git.lumc.nl/humgen/gitcourse.git
    cd gitcourse
    git submodule init
    git submodule update

A new presentation can be added like this:

    cd presentation
    bash mkpres.sh ../mypresentation
