This plugin reads AVS Field files, which can be used to store a variety of volumetric data. This plugin currently supports only a small subset of possible AVS Field file features, specifically it reads files created by AutoDock, for storing potential maps. 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.

Field types
All fields must be "uniform". "Irregular" and "rectilinear" fields are not yet supported.

Data format
Only ASCII files with data stored as floating-point numbers can be read by this plugin. Other combinations of file type and data format cannot be used.

Unit Cell
The unit cell must be three dimensional (ndim and nspace should both be three), and orthogonal.
