   * Conversion from genetic IIDs to standard CATSLife IDs needed to merge PGS output with phenotypic information.
   * Continental ancestry group. These were determined based on mapping CATSLife data to the 1000 Genomes Phase 3 reference panel. EUR (European-like), AFR (African-like), SAS (South Asian-like), and EAS (East Asian-like) groups were classified if they were within 5 SDs of the population means based on the first 4 principal components. Because there is a lot more variability in the AMR (American-like) group, this based on 2 SDs on the first 4 principal components and required that they not already be classified in one of the other groups.
-  * Two sets of PCs are provided in this datafile. Principal components labeled "PC1", "PC2" (etc.) are derived from a PCA within this sample. Principal components labeled "PC1_1KG", "PC2_1KG" (etc.) are derived from mapping our data onto 1000 Genomes. For polygenic scores involving CATSLife data, it is recommended that you use the within-sample PCs, though there may be exceptions.

These PCs were computed based on only one person per family, then the other family members were mapped onto the PCs.
