variant detection: DP and Mendelization
Two questions, which relate to Unified Genotyper or Haplocaller:
Detecting and determining the exact genotype of an individual seems to be inaccurate at read depths less than 10X. This is because there aren't enough reads to accurately say whether it could be heterozygous. Is there an option in either Unified Genotyper or Haplocaller, that excludes sites in individuals that have below 10X? Alternatively how can these sites be removed from the vcf - or set to missing ?
I'm sure I've read somewhere that pedigree information can be supplied to a variant caller (such as Unified Genotyper or Haplocaller), and used to improve the calling accuracy/speed/efficiency. I am calling variants on one parent and multiple offspring.
Apologies if these questions are answered in the user manual. I regularly look it but have not found much to answer my questions.
