fastqc出现错误

先用conda安装

conda install fastqc 

很顺利
输入

fastqc

结果

Exception in thread "main" java.awt.HeadlessException: 
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

可是输入

java -version

java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.15.04.1)
OpenJDK Client VM (build 24.79-b02, mixed mode, sharing)

这个网上说没有图形界面
可以这样

fastqc * .fastq＆

或者

fastqc * .fq.gz＆

都可以

 fastqc *.fq.gz &             [1] 117993
