Note: This page shows how data was organized before the adoption of the BIDS standard. It is preserved here for legacy purposes.

Data stored in the OpenfMRI database conforms to a data organization scheme so that file naming remains consistent across all studies. The scheme is as follows:

Complete specification of a study requires a number of metadata files to be present in the top level directory:

task_key.txt

scan_key.txt

Other files must be present for each model (in models/modelXXX):

condition_key.txt

task_contrasts.txt

In addition, other files may be present that provide further characterization of the data:

demographics.txt
