老师您好，我按照重测序课程的流程一步步处理数据，到最后一步vcftools过滤时出现了问题，起初按照该参数过滤：

vcftools --gzvcf all.varFilter.vcf.gz --recode --recode-INFO-all --stdout \

    --maf 0.05  --max-missing 0.4  --minDP 4  --maxDP 1000  \

    --minQ 30 --minGQ 80 --min-alleles 2  --max-alleles 2 |gzip - > all.clean.vcf.gz

结果是After filtering, kept 0 out of a possible 118111 Sites（中间很多Warning），于是把参数全部拆开一次只过滤一个参数，发现除了--min-alleles 2  --max-alleles 2，可以过滤成功：kept 106816 out of a possible 118111 Sites之外，其他参数全部失败了，结果信息都一样，如下：

--gzvcf 1.vcf.gz

      7         --recode-INFO-all

      8         --max-missing 0.8

      9         --recode

     10         --stdout

     11

     25 After filtering, kept 560 out of 560 Individuals

     26 Outputting VCF file...

     27 After filtering, kept 118111 out of a possible 118111 Sites

请问老师可能原因是什么？
