我是使用蛇制作的新手,在蛇制作上执行步骤gatk VariantRecalibrator时遇到问题,它生成了错误,但是如果使用非蛇制作格式,则脚本可以无错误地运行。

Exiting because a job execution failed. Look above for error message

如果我使用相同的代码,则可以运行以创建recal文件和档次,并可以转到下一步applyvqsr,但是,如果将其放在snakemake中,它会出错并且第27行是gatk --java-options -Xmx16g VariantRecalibrator是错误,但我不知道这是什么错误。请指教。
答案 0 :(得分:0)
我建议您使用--printshellcmds
参数运行Snakemake。这将为您提供在外壳程序中运行的确切命令(而不是您从python胆量获得的异常中获得的命令)。您可以复制该命令并手动运行。
让我澄清一下:Snakemake运行的命令不是您在shell
部分中指定的,但是它运行一个子进程,添加其他参数并设置环境变量(这取决于外壳程序和操作系统) ,然后使用python工具运行应用程序。使用--printshellcmds
参数运行Snakemake将使您看到的命令没有格式问题(当所有通配符都解决时),但没有诸如set -euo pipefail;
这样的细节开销。
