 This folder contains the converted BIDS data files and other files we want to version control using `Datalad`. Since we are storing the entire dataset in the dataverse, we also store the raw xdf files and the associated stimulus/behavioral files in the dataverse. The folder structure is as follows:
 ```
 └── bids

     └── code
         └── log files
