For dump files in molfile format, the x, y, z, vx, vy, and vz fields can be specified. Upon writing VMD will currently only write "atom" style dump files. The cfg constructor takes an object that stores atom snapshots ( dump , data ) as its first argument. Both topology and coordinate parsing functionality is kept in this class as the topology and coordinate reader share many common functions By default the parser expects either atomic or full atom_style however this can be by passing an atom_style keyword argument, see Atom styles. xyz gives vmd no info on atom types and bonding.

Use from write_dump: It is possible to use these dump styles with the write_dump command. It runs on a variety of different computer systems, including single processor systems, distributed-memory machines with MPI, and GPU and Xeon Phi systems. Description. LAMMPS's built-in dump local style can be used to access the positions of the clusters themselves, rather than the locations of each atom or empty site included in them (which is what dump frenkel generates). Overriding the default mapping can be useful, for example, if the file columns containing the particle positions do not have the standard names x, y, and z (e. Thread Tools: Search this Thread # 1 1.
