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 Please cite the following reference if you use these data: Wakeman, D.G. & Henson, R.N. (2015). A multi-subject, multi-modal human neuroimaging dataset. Sci. Data 2:150001 doi: 10.1038/sdata.2015.1 The data have been used in several publications including, for example: Henson, R.N., Wakeman, D.G., Litvak, V. & Friston, K.J. (2011).

This procedure is illustrated here: http://neuroimage.usc.edu/brainstorm/CoordinateSystems#Subject_Coordinate_System_.28SCS_.2F_CTF.29 and in task-facerecognition_fidinfo.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 FAMOUS 6 Immediate Repeat Famous Face FAMOUS 7 Delayed Repeat Famous Face FAMOUS 13 Initial Unfamiliar Face UNFAMILIAR 14 Immediate Repeat Unfamiliar Face UNFAMILIAR 15 Delayed Repeat Unfamiliar Face UNFAMILIAR 17 Initial Scrambled Face SCRAMBLED 18 Immediate Repeat Scrambled Face SCRAMBLED 19 Delayed Repeat Scrambled Face SCRAMBLED stimuli/meg/ ------------ 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.
