This plugin reads electron density maps stored in the PLT format used by gOpenMol. More information on this file format can be found at


This plugin is used only to read files. VMD does not currently support writing this file type.

Unused data
VMD ignores the "surface type" value.

Unit Cell
Since PLT files don't contain any information about the geometry of the unit cell, it is assumed that the basis vectors are orthogonal.

ASCII and Binary Files:
This plugin can read binary plt files regardless of the byte-order of the platform used to create them. It does not currently support the "formatted ASCII" files used by the pltfile program included with gOpenMol.
