This dataset was originally acquired and shared by Daniel Wakeman and Richard Henson (https://pubmed.ncbi.nlm.nih.gov/25977808/). The data has been repackaged in EEGLAB format and has undergone minimal preprocessing as well as reorganization and annotation of the dataset events. + +**Overview of the experiment:** +Eighteen participants completed two recording sessions spaced three months apart – one session recorded fMRI and the other simultaneously recorded MEG and EEG data. During each session, participants performed the same simple perceptual task, responding to presented photographs of famous, unfamiliar, and scrambled faces by pressing one of two keyboard keys to indicate a subjective yes or no decision as to the relative spatial symmetry of the viewed face. Famous faces were feature-matched to unfamiliar faces; half the faces were female. The two sessions (MEEG, fMRI) had different organizations of event timing and presentation because of technological requirements of the respective imaging modalities. Each individual face was presented twice during the session. For half of the presented faces, the second presentation followed immediately after the first. For the other half, the second presentation was delayed by 5-15 face presentations. + +**Preprocessing:** +The preprocessing, which was performed using the `wh_extracteeg_BIDS.m` located in the code directory, includes the following steps: +* Ignore MRI data except for sMRI. +* Extract EEG channels out of the MEG/EEG fif data +* Add fiducials +* Rename EOG and EKG channels +* Extract events from event channel +* Remove spurious events 5, 6, 7, 13, 14, 15, 17, 18 and 19 +* Remove spurious event 24 for subject 3 run 4 +* Rename events taking into account button assigned to each subject +* Correct event latencies (events have a shift of 34 ms) +* Resample data to 250 Hz (this step is performed because this dataset is used in a tutorial for EEGLAB and needs to be lightweight) +* Remove event fields `urevent` and `duration` +* Save as EEGLAB .set format + +**Data curators:** +Ramon Martinez, Dung Truong, Scott Makeig, Arnaud Delorme (UCSD, La Jolla, CA, USA), Kay Robbins (UTSA, San Antonio, TX, USA) + diff --git a/tests/data/bids_tests/eeg_ds003645s_empty/dataset_description.json b/tests/data/bids_tests/eeg_ds003645s_empty/dataset_description.json new file mode 100644 index 00000000..ab5887cd --- /dev/null +++ b/tests/data/bids_tests/eeg_ds003645s_empty/dataset_description.json @@ -0,0 +1,24 @@ +{ + "Name": "Face processing MEEG dataset with HED annotation", + "BIDSVersion": "1.9.0", + "HEDVersion": "8.2.0", + "License": "CC0", + "Authors": [ + "Daniel G.
