XCrySDen
========

Description
-----------

XCrySDen is a crystalline and molecular structure visualisation program, which aims at display of isosurfaces and contours, which can be superimposed on crystalline structures and interactively rotated and manipulated.

It is quite old but still useful and recently there has been some renewed development activity.

User instructions
-----------------

XCrySDen is installed on all workstations from the Debian repositories.

The main program is xcrysden, though several other programs exist which may or (more likely) may not be useful to the end user.

Note XCRYSDEN_SCRATCH defines the directory for writing temporary files.  XCrySDen can produce lots of temporary output, so I suggest setting it to ``/workspace/$USER/.xcrysden`` in your environment if you use XCrySDen often.

Admin notes

The version from the Debian repositories is sufficiently recent currently.
