我正在尝试在管道时并行运行命令。原因是中间文件太大而无法保存,所以我可以丢弃它们
我有以下代码,它们可以单独工作:
#fixmate and convert to bam
parallel --verbose --link -j 4 'samtools fixmate -O bam,level=1 {1} /home/Teste1/samtools/unsorted/{/.}.bam -@ 8' ::: /home/Teste1/star/twopassoverhang/*.fqAligned.out.sam
#sort according to coordinate
parallel --verbose --link -j 4 'samtools sort {1} -o /home/Teste1/samtools/sorted/{/.}-sorted.bam -@ 8' ::: /home/Teste1/samtools/unsorted/*.bam
#index bam files
parallel --verbose --link -j 4 'samtools index {1} -@ 8' ::: /home/Teste1/samtools/sorted/*-sorted.bam
我试过了:
parallel --verbose --link -j 4 'samtools fixmate -O bam,level=1 {1} - -@ 4 | / #fixmate and output bam to nextcommand
samtools sort - - -@ 4 | / #sort bams
tee /home/Teste1/samtools/sorted/{/.}-sorted.bam | / #save sorted bam file to disk
samtools index - -@ 4' ::: /home/Teste1/star/twopassoverhang/*.fqAligned.out.sam #creates index
但我通过 --dry-run 得到以下信息:
samtools fixmate -O bam,level=1 '/homeTeste1/star/twopassoverhang/101_FRAS202421991-1a_1.fqAligned.out.sam' - -@ 4 |
samtools sort - - -@ 4 |
tee /home/Teste1/samtools/sorted/101_FRAS202421991-1a_1.fqAligned.out-sorted.bam |
samtools index - -@ 4
跑步给了我:
samtools index: "-" is in a format that cannot be usefully indexed
samtools fixmate -O bam,level=1 '/home/Teste1/star/twopassoverhang/12_FRAS202372578-2r_1.fqAligned.out.sam' - -@ 4 | samtools sort - - -@ 4 | tee /home/Teste1/samtools/sorted/12_FRAS202372578-2r_1.fqAligned.out-sorted.bam | samtools index - -@ 4
[bam_sort] Use -T PREFIX / -o FILE to specify temporary and final output files
Usage: samtools sort [options...] [in.bam]
我尝试了其他一些变化,但没有成功。有任何想法吗?
