Expand Multiallelic Genotypes
This process creates a data set containing columns of expanded genotypes for simple-sequence repeats (SSRs) or other multiallelic markers. The output data set contains one column per allele at each marker, with either dominant coding indicating the presence of that allele in the marker or additive coding indicating the number of copies of that allele the genotype comprises. An updated annotation data set is created as well, with one row per marker allele for all alleles that are included in the genotype data set.
What do I need?
One SAS Input Data Set containing multiallelic genotype data is required by this process. The ssr_example.sas7bdat data set serves as an example and is shown below. It is a wide data set, containing 13 columns (a sample identifier, a measure of the quantitative trait , and 11 marker variables ) and 200 rows (corresponding to samples).
An Annotation Data Set is optional . An annotation data set contains information, such as gene identity or chromosomal location, for each of the markers. Annotation data sets are tall data sets; each row corresponds to a different marker.
For detailed information about the files and data sets used or created by JMP Life Sciences software, see Files and Data Sets .
Output from this process is accessed from a Results window. Refer to the Expand Multiallelic Genotypes output documentation for detailed descriptions and guides to interpreting your results.
