vcffixup (VCF transformation) |
VCFFIXUP(1) |
Generates a VCF stream where AC and NS have been generated for each record using
sample genotypes
-
Count the allele frequencies across alleles present in each record in the VCF file. (Similar to vcftools --freq.)
Uses genotypes from the VCF file to correct AC (alternate allele count), AF
(alternate allele frequency), NS (number of called), in the VCF records. For
example:
% vcfkeepsamples file.vcf NA12878 | **vcffixup** - | vcffilter -f "AC > 0"
Would downsample file.vcf to only NA12878, removing sites for which the sample
was not called as polymorphic.
Type: transformation
