Multisubject, multimodal face processing


This dataset was obtained from the OpenNeuro project (https://www.openneuro.org). Accession #: ds000117

The same dataset is also available here: ftp://ftp.mrc-cbu.cam.ac.uk/personal/rik.henson/wakemandg_hensonrn/, but in a non-BIDS format (which may be easier to download by subject rather than by modality)

Note that it is a subset of the data available on OpenfMRI (http://www.openfmri.org; Accession #: ds000117).

Description: Multi-subject, multi-modal (sMRI+fMRI+MEG+EEG) neuroimaging dataset on face processing

func/

---

Unlike in v1-v3 of this dataset, the first two (dummy) volumes have now been removed (as stated in *.json), so event onset times correctly refer to t=0 at start of third volume

Note that, owing to scanner error, Subject 10 only has 170 volumes in last run (Run 9)

meg/

---

Three anatomical fiducials were digitized for aligning the MEG with the MRI: the nasion (lowest depression between the eyes) and the left and right ears (lowest depression between the tragus and the helix, above the tragus). This procedure is illustrated here: http://neuroimage.usc.edu/brainstorm/CoordinateSystems#SubjectCoordinateSystem.28SCS.2FCTF.29 and in task-facerecognitionfidinfo.pdf

The following triggers are included in the .fif files and are also used in the “trigger” column of the meg and bold events files:

Trigger Label Simplified Label

5 Initial Famous Face IniFF 6 Immediate Repeat Famous Face ImmFF 7 Delayed Repeat Famous Face DelFF 13 Initial Unfamiliar Face IniUF 14 Immediate Repeat Unfamiliar Face ImmUF 15 Delayed Repeat Unfamiliar Face DelUF 17 Initial Scrambled Face IniSF 18 Immediate Repeat Scrambled Face ImmSF 19 Delayed Repeat Scrambled Face DelSF

The .bmp files correspond to those described in the text. There are 6 additional images in this directory, which were used in the practice experiment to familiarize participants with the task (hence some more BIDS validator warnings)

The .bmp files correspond to those described in the text.

Defacing

---

Defacing of MPRAGE T1 images was performed by the submitter. A subset of subjects have given consent for non-defaced versions to be shared - in which case, please contact rik.henson@mrc-cbu.cam.ac.uk.

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/

Relationship of Subject Numbering relative to other versions of Dataset

---

There are multiple versions of the dataset available on the web (see notes above), and these entailed a renumbering of the subjects for various reasons. Here are all the versions and how to match subjects between them (plus some rationale and history for different versions):

1. Original Paper (N=19): Wakeman & Henson (2015): doi:10.1038/sdata.2015.1

Number refers to order that tested (and some, eg 4, 7, 13 etc were excluded for not completing both MRI and MEG sessions)

1. openfMRI, renumbered from paper: http://openfmri.org/s3-browser/?prefix=ds000117/ds000117_R0.1.1/uncompressed/

Numbers 1-19 just made contiguous

1. FTP subset of N=16: ftp: ftp://ftp.mrc-cbu.cam.ac.uk/personal/rik.henson/wakemandg_hensonrn/

This set was used for SPM Courses Designed to illustrate multimodal integration, so wanted good MRI+MEG+EEG data for all subjects Removed original subject01 and subject06 because bad EEG data; subject19 because poor EEG and fMRI data (And renumbered subject14 for some reason).

1. Current OpenNeuro subset N=16 used for (BIDS): https://openneuro.org/datasets/ds000117

OpenNeuro was rebranding of openfMRI, and enforced BIDS format Since this version designed to illustrate multi-modal BIDS, kept same numbering as FTP
