Question

我正在尝试在RNA seq（.fastq）上运行fastqc，我得到了这个我还没有设法修复的问题：

最后，我得到一个空的fastqc.zip文件。没有HTML报告...... 我在CentOS 7.3上运行它，我的java版本是：

openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

有人能帮助我吗？提前谢谢！

这里也有同样的问题，唯一成功的方法是删除我的apt版本（因为mattbull说here，“从能力上来的FastQC已经被打破了很久了”）：

options = {0 : zero,
           1 : sqr,
           4 : sqr,
           9 : sqr,
           2 : even,
           3 : prime,
           5 : prime,
           7 : prime,
}

def zero():
    print "You typed zero.\n"

def sqr():
    print "n is a perfect square\n"

def even():
    print "n is an even number\n"

def prime():
    print "n is a prime number\n"

options[num]()

然后注销并登录到您的实例以重置PATH。

然后，在Anaconda中搜索0.11.8 FastQC版本，因为我们知道软件包中已包含运行良好的jdk版本。

sudo apt-get purge fastqc

然后，用

安装

conda search -c bioconda fastqc

至少只有这样，错误才对我消失，我可以正常使用FastQC。

FastQC无法处理fastq序列文件 - java.lang.NullPointerException
