<commit_before># 3D print your brain

So, you want to 3D print your own brain? The following is a step by step guide that will show you how you can 3D print a brain, all coming from a structural image (T1) like this:

![brain](static/brain.png "Brain - T1 image" =400x)

**Note:** To create a 3D surface model of your brain we will use FreeSurfer and meshlab. Therefore you should make sure that those two softwares are already installed on your system.


1. Specify Variables
--------------------

Let's first specify all necessary variables that we need for this to work:

```bash
export EXPERIMENT_DIR=/users/mnotter/tmp
export SUBJECTS_DIR=$EXPERIMENT_DIR/freesurfer
export subjectName=sub001<commit_msg>TST: test for rst<commit_after># 3D print your brain
