Over 100 Task fMRI Dataset by Tomoya Nakai and Shinji Nishimoto

References: Nakai & Nishimoto (bioRxiv 2019, doi: https://doi.org/10.1101/614081) Nakai & Nishimoto (Nature Communications 2020, doi: https://doi.org/10.1038/s41467-020-14913-w)

We measured brain activity using functional MRI while six subjects (“sub-01”, …, “sub-06”) performed 103 cognitive tasks.

The entire folder consists of subject-wise subfolders (“sub-01”,…). Each subject’s folder contains the following subfolders: 1) anat: T1-weighted structural images 2) func: functional signals (multi-band echo-planar images)

Each subject performed 18 runs consisting of 12 training runs and 6 test runs. The training and test data were assigned with the following notations: Training data: sub-0*_task-training_run-**_bold.json Test data: sub-0*_task-test_run-**_bold.json

Each *_event.tsv file contains following information: ONSET: stimulus onset DURATION: stimulus duration TRIAL_TYPE: task type (out of 103 tasks)

The analysis codes and preprocessed data that were used in the original article are available at Open Science Framework (OSF, https://osf.io/ea2jc/).

Caution This dataset can be used for research purposes only. The data were anonymised, and users shall not perform analyses to re-identify individual subjects.

Hi. In your paper you state that "In addition to the task, 6 s of imaging without a task was inserted at  the beginning and at the end of each run; the former was discarded in  the analysis." Are these volumes already discarded in the fMRI data that is uploaded here? Thanks!

Sorry for the late response, The initial 6s volumes are included in the dataset here. In the preprocessed data uploaded in OSF (https://osf.io/ea2jc/), these volumes are discarded.
