Step 1: Data Preparation

1. Data Recording using your device

Record the EEG data using your own device and document key metadata. Note the participant’s head circumference and ensure you know the names and functions of all non-EEG channels, such as EOG or EMG.

2. Convert recorded data into .edf format

  • Currently only European Data Format - .edf files can be converted. If you acquire data in a different data format (e.g., BrainVision Core Data Format - .vhdr, .vmrk, .eeg or EEGLab data format - .set, .fdt) please convert your data into .edf format or reach out to one of our Data Stewards to work on a solution for an additional format. Additionally, it is assumed that one .edf file contains data of one session of a single participant.

Here are useful links if you don’t have your own script for the conversion:

3. Create your project in the ANC repository

Get the ANC account and gain access to your working group. If your research unit group is not listed, please request its creation by sending an email to anc@plus.ac.at. Include the following details in your email: your username, the full name of the group, its abbreviated name (used in URLs), and a brief description.

Once you have an account and access to your research unit group, create your project using the study acronym and familiarize yourself with the provided files.

4. File naming requirements (.edf files)

Refer to the guidelines provided below for the required naming format:

The filename for the .edf file contains information about the group, study and the subject. Some of the information you can find in the URL to your project.

Workflow

Pattern of the .edf filename: group_project_subject_session.edf

Info Example Description
Group sleep The group identifier of your lab used in the ANC URL
Study vsl-fieldstudy-3 The project name as shown in the ANC URL
Subject S001 The subject identifier (alphanumeric)
Session 1 The information about the session is required even if only one recording session has taken place (alphanumeric).

Since all parts of the .edf filename are separated by _, avoid using _ elsewhere in the filename. Please make sure that the subject and session identifier only contain alphanumeric stings.

Example filename:

  • sleep_vsl-fieldstudy-3_S001_1.edf

Follow the strict file naming convention for .edf files to ensure your data is properly converted and available on the ANC. Incorrectly named files are not processed correctly.
