In addition to true variation, variant callers emit a number of false-positives. Some of these false-positives can be detected and rejected by various statistical tests. VariantAnnotator provides a way of annotating variant calls as preparation for executing these tests.
Description of the haplotype score annotation
The list below is not comprehensive. Please use the
--list argument to get a list of all possible annotations available. Also, see the FAQ article on understanding the Unified Genotyper's VCF files for a description of some of the more standard annotations.
Note that technically the VariantAnnotator does not require reads (from a BAM file) to run; if no reads are provided, only those Annotations which don't use reads (e.g. Chromosome Counts) will be added. But most Annotations do require reads. When running the tool we recommend that you add the
-L argument with the variant rod to your command line for efficiency and speed.
