7 The Command Line tool: dx

The DnaNexus command line tool is loaded as a module on Biowulf. It’s not allowed on the head node, so generally the easiest way to use it is via an interactive session.

[hartleys@biowulf ~]$ sinteractive
[hartleys@cn3145 ~]$ module load DNAnexus

The first thing you will need to do is login to Dna Nexus. This exchanges a key pair, so you won’t have to type in a password every time you use dx. Once you type in your password you will be asked to select a project.

[hartleys@cn3145 ~]$ dx login
