BIDS for behavioral studies

How to store your data in bids structure if you are using psychtoolbox

Resources

Software:

bids-matlab |

bids-starter-kit on GitHub |

JSONio on GitHub

How to implement

You may use the template in the BIDS starter kit (bids-starter-kit/general). Simply copy the corresponding mat file and modify the variables for your project.

After preprocessing:

create_events_tsv_json_full.m

Before finalizing everything:

createBIDS_participants_tsv.m

createBIDS_dataset_description_json.m

Pipeline for transriv project as an example

• Add ‘transriv-bids’ to matlab path

• Go to the root_dir or use the full path of root_dir as input to the functions

• Preprocess data from a subject:

createBIDS_beh_after_preprocessing(root_dir, ‘transriv’, ‘S001’, ‘Rivalry’, ‘GG’)

• Create dataset files by running transriv_finalizeBIDS.m (when data collection is finished)

The folder structure based on BIDS:

root_dir
  └─ ‘transriv’
        ├─ participants.xlsx
        ├─ participants.tsv
        ├─ participants.json
        ├─ sourcedata
        │     └─ sub-S001
        │         └─ ses-Rivalry
        │               └─ beh
        │                   └─ sub-S001_ses-Rivalry_run-GG_beh.mat
        └─ rawdata
             └─ sub-S001
                 └─ ses-Rivalry
                     └─ beh
                         ├─ sub-S001_ses-Rivalry_run-GG_beh.json
                         └─ sub-S001_ses-Rivalry_run-GG_beh.tsv
