【直播】我的基因组53:几个找变异的软件的效果比较
随便找一个SNP-calling的综述就可以找到一大堆软件的评价,我这里强烈推荐A survey of tools for variant analysis of next-generation genome sequencing data : http://bib.oxfordjournals.org/content/15/2/256.short
如果你在找变异这一个知识点还很模糊,甚至可以花点时间来翻译一下,同时欢迎大家交流自己的学习心得(http://www.biotrainee.com/thread-109-1-1.html 论坛回帖即可)
我很早以前处理外显子数据的时候,就比较过几个软件的找变异的效果,这里就继续沿用上次的思路!
我比较了gatk,freebayes,bcftools,varscan,都是引用率比较高的而且经受了时间的考验的好软件。
它们的下载安装方法是:
## Download and install bcftools
## http://www.htslib.org/download/
## http://www.htslib.org/doc/bcftools-1.0.html
cd ~/biosoft
mkdir bcftools && cd bcftools
wget https://github.com/samtools/bcftools/releases/download/1.3.1/bcftools-1.3.1.tar.bz2
tar xvfj bcftools-1.3.1.tar.bz2
cd bcftools-1.3.1
make
cp bcftools /home/jianmingzeng/biosoft/myBin
~/biosoft/myBin/bin/bcftools --help
## Download and install freebayes
