我是使用snakemake 的新手,在snakemake 上执行步骤gatk VariantRecalibrator 时遇到问题,它产生错误,但脚本在非snakemake 格式时可以正常运行。

Removing output files of failed job vqsr since they might be corrupted:
VCFs/CHS.recal.vcf, VCFs/CHS.output.tranches, VCFs/CHS.output.plots.R
Shutting down, this might take some time.
Exiting because a job execution failed. Look above for error message

如果我使用相同的代码,我可以运行以创建 recal 文件和 tranches,并且可以转到下一步 applyvqsr,但是如果我将它放入 snakemake 它有错误并且第 27 行是 gatk --java-options -Xmx16g VariantRecalibrator是错误,但我不知道它是什么错误。请指教。
