我已经编辑了上一个问题,因为它太长而且烦人,现在我已经找到了我想要的东西,我看到在下面的代码中有一些小故障。寻求建议。

我有代码,现在它按预期工作,但我得到一个额外的0行,我无法理解为什么?有什么建议吗?

#!/bin/bash
#$ -S /bin/bash

cd /path/vdas/client/ChIP-Seq/output/merge_MACS2_peaks_patient_specific/EOC/test

cut -f 1,2,3 /path/vdas/client/ChIP-Seq/output/merge_MACS2_peaks_patient_specific/EOC/test_merge.bed > tmp
printf "chr\tstart\tend" > tsamples
for file in `ls *.bed`; do
    printf "\t" >> tsamples
    printf `basename $file .bed` >> tsamples
    #echo $file | cut -d_ -f 1,2,3 >> tsamples
    intersectBed -wao -a /path/vdas/client/ChIP-Seq/output/merge_MACS2_peaks_patient_specific/EOC/test_merge.bed -b $file -f 0.20 | cut -f 9 | tail -n+1 | paste tmp - > tmp2
    mv tmp2 tmp
done
echo "" >> tsamples
cat tsamples tmp > histone_marks.map
rm tsamples tmp

输出

一切都很好,除了最后一行显示0,不知道为什么?任何建议

1 个答案:

答案 0 :(得分:1)

我相信我做的正确,所以我自己更改了代码,这就是我做的方式

#!/bin/bash
#$ -S /bin/bash

cd /path/vdas/client/ChIP-Seq/output/merge_MACS2_peaks_patient_specific/EOC/test

cut -f 1,2,3 /path/vdas/client/ChIP-Seq/output/merge_MACS2_peaks_patient_specific/EOC/test_merge.bed > tmp
printf "chr\tstart\tend" > tsamples
for file in `ls *.bed`; do
    printf "\t" >> tsamples
    printf `basename $file .bed` >> tsamples
    #echo $file | cut -d_ -f 1,2,3 >> tsamples
    intersectBed -wao -a /path/vdas/client/ChIP-Seq/output/merge_MACS2_peaks_patient_specific/EOC/test_merge.bed -b $file -f 0.20 | cut -f 9 | tail -n+1 | paste tmp - > tmp2
    mv tmp2 tmp
done
echo "" >> tsamples
cat tsamples tmp > histone_marks.map
rm tsamples tmp
sed '$d' histone_marks.map

这确实有效,但我知道这是一种非常粗暴的方式。我无法弄清楚为什么最后一行0会出来,但它是用某种操作我相信bash而不是intesectBed操作,因为列非常好。
