This plugin reads formatted DLPOLY HISTORY (trajectory) files, a minimalistic plain text format for storing molecular coordinate trajectories. This plugin can't read binary history files, and may not handle all variants yet but should work for the most common files.

The DLPOLY formatted HISTORY file spcecification is available here


Periodic Cell Data The plugin will read periodic cell information from the DLPOLY history file as long as the cell basis vectors are orthogonal. The plugin doesn't presently convert non-orthogonal DLPOLY unit cell basis vectors to alpha/beta/gamma cell angles.

Unused Data
This plugin only reads the index and coordinates for each atom. Any additional data recorded for an atom is ignored presently.
