Data collection and management
Biological sampling and MRI scanner protocol are described in Standard Operating Procedures. Details about the actual MRI sequences used by each centre are available via SFTP:
All other data have been collected using Psytools. The Excel resource file used to build the Psytools questionnaires is available via SFTP only:
Some of the questionnaires are used under restrictive licensing, therefore this Excel resource file must remain within the c-VEDA consortium. Please do not disseminate.
We have written specific software and scripts for imaging data collection and further data processing. We have published and maintain them in GitHub. We roughly describe the data acquisition and management process from the perspective of the databank operators in the cveda_databank wiki.
We release formal versions of the c-VEDA dataset, appending additional data or fixing existing data with each release:
