What is a .VHDR file?
VHDR is the header of a BrainVision EEG recording.
- Did you know
- The BrainVision format from Brain Products GmbH splits a recording into a .vhdr header, a .vmrk marker file and a binary .eeg data file.
- The .vhdr and .vmrk text files follow the Windows INI layout, and the format is one of the EEG formats recommended by the BIDS standard.
- Splitting a recording into a tiny text header and a separate large binary data file lets tools read the channel and montage setup without loading gigabytes of EEG.
- 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
- .VHDR 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 .VHDR file
- Drag a .VHDR 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.
