Downloading Control Genotype Data

To access control data, customers need to download and install the standalone software application, iControlDB Client onto their local computer. This user-friendly software enables easy searching and filtering of the database samples based on criteria such as genotyping product, phenotype, ethnicity, and age. Selected control data can then be downloaded via the standalone application as either raw genotype information, or as a combined final case report generated in GenomeStudio or BeadStudio. Raw intensity data are not currently available for download.
