SNP应仅由正向reads或仅反向reads涵盖。 vcffilter -f "SAF / SAR > 100 & SRF / SRR > 100 | SAR / SAF > 100 & SRR / SRF > 100" -s DP3g95p5maf05.fil1.vcf > DP3g95p5maf05.fil2.vcf 这次的过滤是基于比例,因此一些无关的reads不会删除整个基因座。简单来说,它保留的位点比反向交替rea...
--snp 根据vcf文件第三列ID列的snp名进行过滤。 --snps FILE,--exclude 根据ID文件进行过滤 变异类型过滤 --keep-only-indels --remove-indels 即保留或去除SNP,留下INDEL。 根据VCF文件第七列FILTER进行过滤 --remove-filterer-allFILTER列除了PASS保留,其余都过滤 --keep-filtered,--remove-filtered保留或去除...
ncludes or excludes all sites marked with a specific FILTER flag. These options may be used more than once to specify multiple FILTER flags.自己理解下就好 根据INFO过滤 –keep-INFO –remove-INFO Includes or excludes all sites with a specific INFO flag. These options only filter on the presence...
You can use VCFtools to filter out variants or individuals based on the values within the file. For example, to filter the sites within a file based upon their location in genome, use the options--chr,--from-bp, and--to-bpto specify the region. ./vcftools --vcf input_data.vcf --chr...
And the "--mask-min" option specifies a threshold mask value between 0 and 9 to filter positions by. The default threshold is 0, meaning only sites with that value or lower will be kept. SITE ID FILTERING --snp Include SNP(s) with matching ID (e.g. a dbSNP rsID). This command ca...
The resulting output file has the suffix '.snpden'. --TsTv <int> Calculates the Transition / Transversion ratio in bins of size defined by this option. The resulting output file has the suffix '.TsTv'. A summary is also supplied in a file with the suffix '.TsTv.summary'. --FILTER...
And the "--mask-min" option specifies a threshold mask value between 0 and 9 to filter positions by. The default threshold is 0, meaning only sites with that value or lower will be kept. SITE ID FILTERING --snp <string> Include SNP(s) with matching ID (e.g. a dbSNP rsID). This...
