Allele calls are made for a sample by comparing its sense and antisense
strand RAS values to a SNP model, created using Modified
Partitioning Around Medoids (MPAM), in the mapping algorithm.
Each SNP in the model has
medoids
defined for the AA, AB, and BB
alleles
. The sample’s sense and antisense RAS values are
compared to the SNP’s model medoids to derive the
call zone score
for the sample, also known as the Distance to Radius (DTR) ratio. If a
sample’s call zone score for an allele’s medoid is less than a predefined
quantity, known as the
call zone radius
or call zone bound (default
value = 0.8), the sample is assigned that allele call. A call zone score
near 0 indicates a high confidence in the accuracy of the call. Call zone
scores near the call zone radius value indicate less confidence in the
accuracy of the call.
