cohortId | Unique cohort identifier within the study. |
sampleCount | Count of samples with non-missing genotypes in this variant from the cohort. |
fileCount | Count of files with samples from the cohort that reported this variant. |
alleleCount | Total number of alleles in called genotypeCounters. It does not include missing alleles. |
refAlleleCount | Number of reference alleles found in this variant. |
refAlleleFreq | Reference allele frequency calculated from refAlleleCount and alleleCount, in the range [0,1] |
altAlleleCount | Number of main alternate alleles found in this variants. It does not include secondary alternates. |
altAlleleFreq | Alternate allele frequency calculated from altAlleleCount and alleleCount, in the range [0,1] |
missingAlleleCount | Number of missing alleles. |
missingGenotypeCount | Number of genotypes with all alleles missing (e.g. ./.). It does not count partially missing genotypes like "./0" or "./1". |
genotypeCount | Number of occurrences for each genotype. |
genotypeFreq | Genotype frequency for each genotype found calculated from the genotypeCount and samplesCount, in the range [0,1] |
maf | Minor allele frequency. Frequency of the less common allele between the reference and the main alternate alleles. |
mafAllele | Allele with minor frequency. |
mgf | Minor genotype frequency. Frequency of the less common genotype seen in this variant. |
mgfGenotype | Genotype with minor frequency. |
filterCount | The number of occurrences for each FILTER value in files from samples in this cohort reporting this variant. |
filterFreq | Frequency of each filter calculated from the filterCount and filesCount, in the range [0,1] |
qualityCount | The number of files from samples in this cohort reporting this variant with valid QUAL values. |
qualityAvg | The average Quality value for files with valid QUAL values from samples in this cohort reporting this variant. |
