What is a .CUBE file?
CUBE stores volumetric data such as electron density from chemistry simulations.
- Did you know
- A cube file maps a property like electron density across a 3D grid.
- The format is named after the Gaussian quantum-chemistry package and stores its grids in atomic units of Bohrs and electron charge.
- Beyond the volumetric grid, a cube file also records the positions of every atom in the molecule.
- 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
- .CUBE 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 .CUBE file
- Drag a .CUBE 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.
