现在gatk已经更新到gatk4了，但是gatk3.8还是有很多应用的场景，比如指定多线程，并且有些功能在gatk4里找不到（也可能是我道行浅）所以记录一下之前如何安装和注册gatk3.8的过程，以备不时之需。
用conda安装gatk
conda的安装及使用请参考conda的安装与使用
# 创建一个叫GATK的虚拟环境，并安装gatk
$ conda create -n GATK GATK -y
# 激活这个虚拟环境
$ conda activate GATK
# 尝试运行
$ GenomeAnalysisTK -h
# 或者运行gatk3 -h
会有如下提示：
GATK jar file not found. Have you run "gatk3-register"?
需要运行gatk3-register来注册，运行之后：
$ gatk3-register
It looks like GATK has not yet been installed.
Usage: gatk3-register /path/to/GenomeAnalysisTK[-3.8.tar.bz2|.jar]
Due to license restrictions, this recipe cannot distribute
and install GATK directly. To fully install GATK, you must
download a licensed copy of GATK from the Broad Institute:
https://www.broadinstitute.org/gatk/download/
and run (after installing this package):
gatk-register /path/to/GenomeAnalysisTK[-3.8.tar.bz2|.jar],
This will copy GATK into your conda environment.
到https://software.broadinstitute.org/gatk/download/archive这个地方下载register工具。选择了一个3.8.0的版本，下载到本地，再通过rz传到服务器上（如何无root安装lrzsz请查看无root安装软件系列），解压到~/biosoft下(嗯，习惯把生信相关的软件都存放在家目录的biosoft文件夹下，跟我洲更学长@徐洲更hoptop学的)。重新register一遍。
$ gatk3-register ~/biosoft/GenomeAnalysisTK-3.8-0-ge9d806836.tar.bz2
ENV_PREFIX /my/path/to

jar file specified matches expected version
Moving GenomeAnalysisTK-3.8-0-ge9d806836.tar.bz2 to /my/path/to/gatk-3.8
然后就可以正常使用了
GenomeAnalysisTK -h
# 或者
gatk3 -h
tips：如果需要安装GATK4的话需要在conda里搜索并安装GATK4
# 搜索，非必须步骤
conda search GATK4
# 安装
conda install GATK4
