Annotators

Individual VCFs can be annotated using custom annotators. Currently available annotators:

• coverage - Annotates with information about _mean_ and _dev_ of the depth in the VCF (using DP from INFO).

The data can be accessed from the metadata field in the VCF in the following way:

r = vcf.Reader(filename="/path/to/vcf")
print r.metadata["coverageMetaData"][0]["mean"]
print r.metadata["coverageMetaData"][0]["dev"]
