The data table contains mapping of study subject IDs to sample IDs. Samples are the final preps submitted for genotyping, sequencing, and/or expression data. For example, if one patient (subject ID) gave one sample, and that sample was processed differently to generate 2 sequencing runs, there would be two rows, both using the same subject ID, but having 2 unique sample IDs. The data table also includes a mapping of sample IDs to other sample ID aliases and sample use (SNP_Array, WES_SRA, WGS_SRA, and totRNA_Expression).
