OVITO provides file readers for a variety of input formats, in particular data formats written by molecular dynamics and other atomistic simulation codes. In addition, it can load and visualize other kinds of data, for example triangle meshes and voxel data (grid fields).
File format | Description | Importable data types |
---|---|---|
LAMMPS dump | File format used by the LAMMPS molecular dynamics code. OVITO supports both text-based and binary dump files. | particles |
LAMMPS data | File format used by the LAMMPS molecular dynamics code. | particles, bonds, angles, dihedrals, impropers |
XYZ | Simple column-based text format for particle data, which is documented here. OVITO can read the extended XYZ format, which supports arbitrary sets of particle data columns, and can store addtional information such as the simulation cell geometry and boundary conditions. | particles |
POSCAR / XDATCAR / CHGCAR | File formats used by the ab initio simulation package VASP. OVITO can import atomistic configurations and also charge density fields from CHGCAR files. | particles, voxel grids |
IMD | File format used by the molecular dynamics code IMD. | particles |
CFG | File format used by the AtomEye visualization program. | particles |
DL_POLY | File format used by the molecular simulation package DL_POLY. | particles |
PARCAS | Binary file format written by the MD code Parcas developed in K. Nordlund's group at University of Helsinki. | particles |
NetCDF | Binary format for molecular dynamics data following the AMBER format convention. NetCDF files are produced by the LAMMPS dump netcdf command. | particles |
PDB | Protein Data Bank (PDB) files (experimental support). | particles, bonds |
FHI-aims | Geometry and log-file formats used by the ab initio simulation package FHI-aims. | particles |
GSD/HOOMD | Binary format for molecular dynamics data used by the HOOMD-blue code. See GSD (General Simulation Data) format. | particles |
CASTEP | File format used by the CASTEP ab initio code. OVITO can read the | particles |
XSF | File format used by the XCrySDen program. | particles, voxel grids |
Cube | File format used by the Gaussian simulation package. Specifications of the format can be found here and here. | particles, voxel grids |
GALAMOST | XML-based file format used by the GALAMOST molecular dynamics code. | particles, bonds |
Quantum Espresso | Input data format used by the Quantum Espresso electronic-structure calculation code. | particles |
CIF | Crystallographic Information File format as specified by the International Union of Crystallography (IUCr). Parser supports only small-molecule crystal structures. | particles |
VTK | Format used by the Visualization Toolkit (VTK). This text-based format is documented here. Note that OVITO supports only triangular cells. | triangle meshes |
OBJ | Common text-based format for storing triangle mesh geometry (see here). | triangle meshes |
STL | Another popular format for storing triangle mesh geometry (see here). Note that OVITO supports only STL files in ASCII format. | triangle meshes |
ParaDiS | File format of the ParaDiS discrete dislocation dynamics code. | dislocation lines |
oxDNA | Configuration/topology file format used by the oxDNA simulation code for coarse-grained DNA models. | particles, bonds |
