Header definition line
  • INFO=<ID=FractionInformativeReads,Number=1,Type=Float,Description="The fraction of informative reads out of the total reads">

  • Overview

    The FractionInformativeReads annotation produces a single fraction for each site: sum(AD)/sum(DP). The sum in the numerator is over all the samples in the cohort and all the alleles in each sample. The sum in the denominator is over all the samples.


    • This annotation can be generated by HaplotypeCaller, MuTect2 or GenotypeGVCFs (it will not work when called from VariantAnnotator).

    • DepthPerAlleleBySample displays the number of reads supporting each allele, without calculating the fraction.
