If @arv user current@ is able to access the API server, it will print out information about your account. Check that you are able to access the Arvados API server using the following command:
Access the Arvados Workbench using this link: "https://{{ site.arvados_workbench_host }}/":https://{{ site.arvados_workbench_host }}/ (Replace @{{ site.arvados_api_host }}@ with the hostname of your local Arvados instance if necessary.)
-Open a shell on the system where you want to use the Arvados client. This may be your local workstation, or "an Arvados virtual machine accessed with SSH":{{site.baseurl}}/user/getting_started/ssh-access.html.

h3. Usage
This tutorial demonstrates how to use the Genome Analysis Toolkit (GATK) with Arvados. In this example we will install GATK and then create a VariantFiltration job to assign pass/fail scores to variants in a VCF file.

h2. Installing GATK
To test changes to a script by running a job, the change must be pushed to your hosted repository, and the job might have to wait in the queue before it runs. This cycle can be an inefficient way to develop and debug scripts. This tutorial demonstrates an alternative: using @arv-crunch-job@ to run your job in your local VM. This avoids the job queue and allows you to execute the script directly from your git working tree without committing or pushing.

You will create a job to run the "hash" Crunch script. The "hash" script computes the MD5 hash of each file in a collection.
This tutorial introduces the Arvados Metadata Database. The Metadata Database stores information about files in Keep. This example will use the Python SDK to find public WGS (Whole Genome Sequencing) data for people who have reported a certain medical condition.

In the tutorial examples, three angle brackets (>>>) will be used to denote code to enter at the interactive Python prompt.
This tutorial demonstrates how to use Crunch to run an external program by writting a wrapper using the Python SDK.

In this tutorial, you will use the external program @md5sum@ to compute hashes instead of the built-in Python library used in earlier tutorials.
In this tutorial, we will write the "hash" script demonstrated in the first tutorial.

The Arvados distributed file system is called *Keep*. Keep is a content-addressable file system. This means that files are managed using special unique identifiers derived from the _contents_ of the file, rather than human-assigned file names (specifically, the MD5 hash). This has a number of advantages:
* Files can be stored and replicated across a cluster of servers without requiring a central name server.
A pipeline in Arvados is a collection of crunch scripts, in which the output from one script may be used as the input to another script.
