dlp2dlp allows conversion of a formatted HISTORY file to its unformatted analogue, and vice versa. Note that converting unformatted HISTORY files created on an architecture different from the one you are running dlp2dlp will fail.

Basic Usage

dlp2dlp <HISTORYfile> <format> [nframes]


  • <HISTORYfile> is the target name of the DL_POLY HISTORY file to be written
  • <format> is the desired format of the output file, 0 for unformatted, or 1 for formatted [nframes] (optional) is the number of frames to convert (default = all)




The new HISTORY file is called converted.HISf or converted.HISu, depending on the format requested.
