开箱即用版本 满分室间质评之GATK Somatic SNV+Indel+CNV+SV


本次更新支持基因组版本切换hg19/hg38,以及项目bed文件;方便各种项目切换和适配以及bug修复

最近准备为sliverworkspace 图形化生信平台开发报告设计器,需要一个较为复杂的pipeline作为测试数据,就想起来把之前的 [[满分室间质评之GATK Somatic SNV+Indel+CNV+SV(下)性能优化]]翻出来用一下。跑了一遍发现还是各种问题,于是想把pipeline改造成免部署、首次运行初始化环境的版本,以便需要时候能够直接运行起来,于是有了本文。


一句话描述就是:开箱即用的pipeline,能够根据样本version_reference自动选择参考基因组版本,根据project_bed文件选择项目bed,自动初始化环境、安装所需软件、下载ref文件和数据库的版本


为了让pipeline能够直接运行,无需部署,这里使用docker容器保证运行环境的一致性:见文章:基于docker的生信基础环境镜像构建,这里采用的方案是带ssh服务的docker+conda环境,整个pipeline在一个通用容器中运行。


本文代码较长,可能略复杂,想直接运行的可以下载 workflow文件,导入sliverworkspace图形化生信平台直接运行,获取并查看图形化分析报告

相关代码和workflow文件可以访问笔者github项目地址导入操作

分析流程整体概览




docker 镜像拉取及部署配置

# 拉取docker镜像
docker     pull     doujiangbaozi/sliverworkspace:1.10docker-compose.yml配置文件

version: "3"
services:
   GATK:
     image: doujiangbaozi/sliverworkspace:1.10
     container_name: GATK
     volumes:
       - /home/sliver/Data/data:/opt/data:rw                                #挂载输入数据目录
       - /home/sliver/Manufacture/gatk/envs:/root/mambaforge-pypy3/envs     #挂载envs目录
       - /home/sliver/Manufacture/sliver/ref:/opt/ref:rw                    #挂载reference目录
       - /home/sliver/Manufacture/gatk/result:/opt/result:rw                #挂载中间文件和结果目录
     environment:
       - TZ=Asia/Shanghai                                                   #设置时区
       - PS=20191124                                                        #设置ssh密码
       - PT=9024                                                            #设置ssh连接端口docker 镜像部署运行

# 在docker-compose.yml文件同级目录下运行
docker-compose up -d

# 或者docker-compose -f docker-compose.yml所在目录
docker-compose -f somedir/docker-compose.yml up -d

# 可以通过ssh连接到docker 运行pipeline命令了,连接端口和密码见docker-compose.yml配置文件相关字段
ssh root@127.0.0.1 -p9024
测试数据

测试数据来自2017年卫计委室间质评提供的bed文件(pipeline会自动下载)和测试数据,修改命名以匹配pipeline输入端,也可以替换为自己的数据文件,因为室间质评目前参考基因组还停留在hg19版本,所以本流程仍然使用hg19(GRCH37),如果要切换到hg38,可以将version_reference变量值设置为hg38,project_bed设置为Illumina_pt2_hg38.bed。pipeline会使用hg38(GRCH38)版本和对应的bed文件。
