PREFACE


The installation of the Amsterdam Density Functional band-structure program (BAND) on a computer is explained in the Installation manual, where you can also find information about the license file(s) that you need to run the program. This User's Guide describes how to use the program, how input is structured, what files are produced, and so on.

Where references are made to the operating system (OS) and to the file system on your computer the terminology of UNIX type OSs is used and a hierarchical structure of directories is assumed. Non-UNIX OSs usually have similar features and it should not be difficult to translate the various concepts from UNIX to any other OS language. Currently we only support UNIX systems, although there's no fundamental reason why BAND (and other programs of the ADF suite) would not run under other operating systems.

Release 2000.02

The most important modifications introduced in version 2000.01 (and 2000.02) with respect to the 1999.x releases are:

[Sigma] A new fragment functionality has been implemented, for analysis purposes

[Sigma] Contrary to previous versions, the option to use abbreviated keywords (or extended keywords) has been disabled. This feature caused misunderstanding, confusion and hard-to-catch input mistakes, while it added little convenience. In version 2000.x, keywords must be typed completely and exactly.
Incorrect keywords will go unnoticed and just be ignored (as before).
Most keywords are case insensitive now. Exceptions are of course where file or directory names are involved.
