WebMay 2, 2014 · GATK variant calling generates genotype-level quality metrics including depth of data (DP) and genotype quality (GQ). DP values represent the number of reads passing quality control used to calculate the genotype at a specific site in a specific sample, with higher values for DP generally leading to more accurate genotype calls. VCF, or Variant Call Format, It is a standardized text file format used for representing SNP, indel, and structural variation calls. The VCF specification used to be maintained by the 1000 Genomes Project, but its management and further development has been taken over by the Genomic Data Toolkit team of the Global … See more A valid VCF file is composed of two main parts: the header, and the variant call records. The header contains information about the dataset and relevant reference sources (e.g. the … See more The following is a valid VCF header produced by GenotypeGVCFs on an example data set (derived from our favorite test sample, NA12878).

WebMar 10, 2024 · Convention The convention is it should be in ascending ordering, i.e. 0/1. The question is, why the convention broken? Phasing I think, at a guess, the answer is it depends what reference genome you are using. I would suggest that this result would not occur if the reference genome is mum (or dad) and the alleles are occurring in the child.
