Rare Variant Recoding

This feature enables you to specify how rare variants are coded in the output data set.

Select:	When:
Use Dominant Coding for individual rare variants	To convert rare variant genotypes to the value 1 if the genotype comprises one or more rare alleles and 0 otherwise .
Use Dominant Coding collapsing across rare variants in a group	To c ombine rare variants within an analysis group (such as gene) and coding as 1 if any rare alleles are present and 0 otherwise .
Use Genotype Recoding selected above	T o use the same genotype recoding that is used for non-rare variants.
