What is a .VMRK file?
VMRK holds the event markers for a BrainVision EEG recording.
- Did you know
- The VMRK file notes when each event happened during an EEG session.
- A BrainVision recording is split across three files - the .vhdr header, the .eeg raw data and this .vmrk marker file - that share one base name.
- BrainVision was adopted by the Brain Imaging Data Structure (BIDS) as one of its official EEG and iEEG storage formats.
- 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
- .VMRK 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 .VMRK file
- Drag a .VMRK 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.
