Data Extraction

The Ark, is an expanding collection of population-based epidemiological data. This collection consists of data from studies that are being conducted using The Ark Study Support tools as well as from studies that have been conducted without the benefit of these tools.

Current Studies

The number of studies held within The Ark has been growing steadily since its inception. Our listing of Current Studies should give you a good idea of the range of data we administer.

Data Extraction

The Data Extraction application supports the extraction of data stored within The Ark.

Data Extraction application enables researchers to create custom datasets. A dataset is any set of data that has been extracted from the The Ark database from a particular study. Users may create an unlimited number of datasets. Existing datasets may be edited should the user wish to update the data extracted to reflect the current state of the The Ark database, or to alter the dataset definition in terms of the data of interest.

A researcher's dataset can contain a subset of data from one or more study collections. A collection is a group of data items, either phenotypic or genotypic, that have a relationship that warrants their grouping together within The Ark. The researcher can select data relating to particular phenotypes or genetic markers, for a particular set of subjects.

Once a custom dataset has been created, it can be securely downloaded to your local computer in CSV (comma-separated values) or txt (tab-separated) format.

You can only create datasets from studies that you have been authorised to access. You will need custodian approval to gain this access. To gain access to data from a new or ongoing study, Contact Us.
