README

These 120 MRI datasets are being released to the public along as part of the materials for “Temporal interpolation alters motion in fMRI scans: magnitudes and consequences for artifact detection” by Power et al. in PLOS ONE.

Included for each subject is a T1-weighted anatomical image (MP-RAGE) and one or more T2*-weighted scans (resting state BOLD scans)

All subjects - were “typical” young adults that reported no significant neurological or psychiatric history - were right-handed and reported that English was their first language - were scanned at Washington University in Saint Louis on a Siemens MAGNETOM Tim Trio 3T scanner with a Siemens 12-channel head coil - were scanned using interleaved ascending product sequences for T2* data - were scanned in the eyes-open resting state fixating a white crosshair on a black background

The data have been described in multiple publications from the Petersen/Schlaggar group, - beginning with Power et al., 2013 “Evidence for hubs in human brain networks” in Neuron - and most comprehensively in Power et al., 2014 “Methods to detect, characterize, and remove motion artifact in resting state fMRI” in Neuroimage - as well as several other publications - see these publications for further details on acquisitions and demographics

Becky Coalson of the Petersen/Schlaggar group collated these scans and de-identified them for public release - the accompanying file “WU120_subject_information.txt” contains for each subject - the release subject number (1-120) - the same number used in the present publication - the subject number used in Power et al., 2014 - see the WU120_Supplememtal_Cohort_Illustration.pdf from Power et al., 2014 - the subject number to publicly reference the subject - for question/communication purposes with Becky or the Petersen/Schlaggar group - the owner/contributor of the data - age of subject at scanning - sex - handedness - English only speaker - paradigm of the resting state scans - total scan time in resting state - number of rest runs - number of volumes per run - TR of the runs - scanner used (Siemens Tim Trio was in bay3) - slice order (AFNI convention); sequences were ascending interleaved

If there are questions about the scans, please contact Becky Coalson (becky@npg.wustl.edu) or contact the Petersen/Schlaggar group via their website.

General Comments

Defacing -------- Pydeface was used on all anatomical images to ensure deindentification of subjects. The code can be found at https://github.com/poldracklab/pydeface

Quality Control --------------- Mriqc was run on the dataset. Results are located in derivatives/mriqc. Learn more about it here: https://mriqc.readthedocs.io/en/latest/

Where to discuss the dataset ---------------------------- 1) www.openfmri.org/dataset/ds000243/ See the comments section at the bottom of the dataset page. 2) www.neurostars.org Please tag any discussion topics with the tags openfmri and ds000243. 3) Send an email to submissions@openfmri.org. Please include the accession number in your email.

Known Issues ------------ - As per one of the published paper explaining the dataset, its is noted that 2 subjects out of all have different TR for functional runs. However, when checked with submitter, they confirmed that all subjects data shared here have same TR.

Hello. Is slice timing info available for these scans? It seems to be missing from the fmri .json's. Also, I understand that at some point, the subjects were annotated with information about slice order, in a file called “WU120_subject_information.txt” but I can't find this file either. Cheers, Josh
