We discuss here software infrastructure for databank operations of the c-VEDA project.

Recruitment and acquisition centres

The databank team will collect, curate, and publish data from the following recruitment and acquisition centres:

ID	CENTRE	Affiliation	Location	MRI

From acquisition centres to databank

• Acquisition centres collect clinical and environmental data using Psytools. The databank team download CSV files pseudonymized with PSC1 codes directly from the Delosis server.
• Acquisition centres pseudonymize biological samples at the source using PSC1 codes. The c-VEDA biobank team collect samples and collate genetic data before sending them to the databank.
• Acquisition centres anonymize DICOM files before sending them to the databank. Again subjects are identified by their PSC1 code only.

Databank operations

System software has been installed on the c-VEDA server as described in file /cveda/databank/framework/INSTALL.txt.

Application software has been deployed on the c-VEDA server under /cveda/databank/framework/cveda_databank:

cd /cveda/databank/framework
git clone https://github.com/cveda/cveda_databank.git

Databank operations, based on the above application software, are described in specific pages:

• Pseudonymization: generate PSC1 and PSC2 codes.
• Psytools: download and anonymize Psytools questionnaires from Delosis servers.
• Neuroimaging: collect and process MRI data from acquisition centres.
