What is a .EEG file?
An .eeg file holds an electroencephalography brain-signal recording.
- Did you know
- EEG files store the tiny electrical signals measured from the scalp.
- In the BrainVision format a .eeg file is the raw binary signal data, paired with a .vhdr header and a .vmrk marker file sharing its name.
- The .eeg data is written little-endian without a byte-order mark, and its companion .vhdr explains how to interpret the channels.
- What Analyser reads
- Identify and read more scientific, medical and engineering files: R serialized data (RDS/RData), ABIF sequencing traces, VASP/Gaussian/XCrySDen DFT structures, ChemDraw (CDX/CDXML), Axon ABF and NI TDMS instrument data, BrainVision/Neuroscan/EEGLAB EEG, Gmsh/Abaqus/Nastran/ANSYS FEA decks, SPICE netlists, VTK structured/rectilinear grids and oscilloscope waveforms.
- Depth of analysis
- .EEG is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .EEG file
- Drag a .EEG file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
