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). You can download similar test data from our resource bundle and … See more The sample-level information contained in the VCF (also called "genotype fields") may look a bit complicated at first glance, but they are actually not that hard to interpret once you understand that they are just sets of tags … See more For each site record, the information is structured into columns (also called fields) as follows: The first 8 columns of the VCF records (up to and including INFO) represent the … See more 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. google search web
