MEG Data storage

The MEG data is securely stored on NYU BOX, access is given through invitations. The Data folder is structured in the BIDS standardized format. Please raise an issue on github repository if you think the structure does not conform to BIDS.

Data naming and uploading protocol

In the following, [SUB_ID] should be replaced with the ID of the subject for naming purposes. The different data files generated from a MEG experiment are the following.

Note

If you have suggestions to make the naming convention better, please raise an issue on github or create a pull request with your proposed modifications.

Laser scan files

  1. A .fsn filename that should be named sub-\[SUB_ID\]_scan.fsn : This file is obtained by saving the whole fastscan laser project (File Save)

  2. Several .txt

    • sub-[SUB_ID]_scan.txt is the head scan of the participant

    • sub-[SUB_ID]_scan_stylus.txt is the stylus location file of the participant

KIT-MEG files

Depending on the experiment, many .con files can be produced by the KIT machine.

  1. .con files are named: * sub-[SUB_ID]_[date].con

  2. .mrk files are named: * sub-[SUB_ID]_[marker_number]_[date].mrk where [marker_number] is replaced with the number of the marker (representing the time-order of acquisition of that marker)

OPM files

The OPM system generates a BIDS directory with the .fif files

Data uploading

Data will be uploaded to NYU BOX, to the following link

Steps

  1. Access the folder of NYU Box

  2. Identify the project that the data belongs to

  3. Access the folder for that project or create a new folder if non-existent

  4. Follow the BIDS structure format, within each project file, we find subjects file named by their ID

    • Within each subjects folder we find, anat, meg-kit, meg-opm folders

    • Place the corresponding files into the right folder: all headscan files go to anat, the .con and .mrk goes to meg-kit, the .fif goes to meg-opm

  5. Make sure that all files have been uploaded to the folder
