PHI Plugin, Version 0.2

This plugin reads "formatted ASCII" potential maps created by the DelPhi utility format_phi. To read the "unformatted" binary files used by DelPhi, use the grdplugin.

Feature-specific notes:

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

Grid Points
It is assumed that the density values of all files are arranged in a cubic grid.

Unit Cell
Since PHI files do not explicitly state the angles of the basis vectors, it is assumed that they are orthogonal.
