In Strelka vcf in INFO column we have these
Depth="The number of reads covering the variant position including duplicates, supplementary records and reads that fall below minimum base and mapping quality thresholds."
ReadCount="The number of reads covering the variant position excluding duplicates, supplementary records and reads that fall below minimum base and mapping quality thresholds.">
ReadCountControl="The number of reads covering the variant position in the control excluding duplicates, supplementary records and reads that fall below minimum base and mapping quality thresholds.">
And in FORMAT column we have
AU="Number of 'A' alleles used in tiers 1,2">
CU="Number of 'C' alleles used in tiers 1,2">
DP="Read depth for tier1 (used+filtered)">
GU="Number of 'G' alleles used in tiers 1,2">
TU="Number of 'T' alleles used in tiers 1,2">
What is the difference of ReadCount in INFO column and DP in FORMAT column?
What is the difference of number of allele versus number of reads covering the variant position ?
Please help for clarification if you have any intuition on this definitions
Thanks
