Question

我正在运行一个来自EMBL的Perl脚本（在这里找到https://github.com/EMBL-EBI-GCA/reseqtrack/blob/master/scripts/variation_data/calculate_allele_frq_from_vcf.pl）在Ubuntu 16.10下我已根据需要安装了Vcftools和Tabix，两者都经过测试可以正常工作。我使用以下命令执行脚本：

perl /home/[user]/calculate_allele_frq_from_vcf.pl \
-vcf /home/[user]/share/1000genomesPhase3VCFFiles/ALL.chr1.phase3_shapeit2_mvncall_integrated_v5a.20130502.genotypes.vcf.gz \
-sample_panel /home/[user]/share/1000genomesPhase3VCFFiles/integrated_call_samples_v3.20130502.ALL.panel \
-out_dir /home/[user]/Desktop/AlleleFrequency \
-tabix  /home/[user]/tabix-0.2.6 \
-vcftools_dir /home/[user]/vcftools_0.1.13 \
-region 1:1-10000 \
-pop CEU,FIN \

返回以下错误

由于某种原因，该脚本似乎无权访问Tabix。我已经为执行脚本的用户（我）提供了文件夹的完全读/写权限。有什么想法吗？

Answer 1

您将-tabix设置为/home/[user]/tabix-0.2.6，但代码似乎需要可执行文件的路径，而不是顶级目录。将/bin/tabix添加到路径应该可以解决问题。

Perl脚本无法访问Tabix文件夹
