I would really like to use FastQC for my project but am getting the following error message when I try to run it on my Ubuntu server 15.04

```
bio@ubuntu:~$ fastqc &

[1] 716
rafay@ubuntu:~$ Exception in thread "main" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

```

Whereas java is already installed

```
bio@ubuntu:~$ java -version

java version "1.7.0_79"

OpenJDK Client VM (build 24.79-b02, mixed mode, sharing)
```
It is complaining X11 is not set (maybe not even installed?). When you call fastqc without arguments, it opens the graphical interface. Try:

    fastqc *.fastq &
