A dataset containing the ancestry categories defined in NHGRI-EBI GWAS
Catalog framework (Table 1, tools:::Rd_expr_doi("10.1186/s13059-018-1396-2")). Ancestry
categories are assigned to samples with distinct and well-defined patterns of
genetic variation. You will find these categories in the variable
ancestry_category of the following objects: scores,
performance_metrics and sample_sets. Ancestry
categories (ancestry_category) are further clustered into ancestry
classes (ancestry_class).
ancestry_categoriesA data frame with 19 ancestry categories (rows) and 6 columns:
Ancestry category.
To reduce the complexity associated with the many
ancestry categories, some have been merged into higher-level groupings
(ancestry_class). These groupings represent the current breadth of
data in the PGS Catalog and are likely to change as more data is added.
3-letter code for the ancestry_class
e.g. "EUR" or "MAE".
Hexadecimal colour code associated with
ancestry groupings (ancestry_class). This can be useful when
visually communicating about ancestries.
Description of the ancestry category.
