Getting started...
On a Unix (or Linux or Cygwin) system, start Wit!P from a shell-window,
by entering
witnotp &
at the command prompt. The ampersand (&) at the end
of the line tells the command shell to run Wit!P as a background process,
which means that your shell window will remain available for interactions
with the operating system.
On a PC running Windows, start the graphics server by double-clicking
on the WitNotP icon. Then start the client by double-clicking on
the WitNotPC icon (or log into a remote Unix system which has Wit!P
installed, and start the client on the remote system with the witnotp&
command at the shell prompt).
If all goes well, the Wit!P GUI (graphical user interface) will pop
up on your screen:

The Wit!P GUI is divided into three parts:
-
the black 3D window: taking up the largest part of the GUI's real estate.
-
message/command box: 6 text lines below the 3D window. The message/command
box is split up into a scrollable message area (top 5 lines) which will
be used by the program to talk back to the user (display of results, error
messages...) and a 1 line command input area, allowing the user to talk
to the program through the keyboard.
-
menu box: the area to the right of the 3D window and message/command box
may be used as an alternative to command input via the keyboard. The right
mouse button is used to select items from the menu. If you find picking
with the right button irritating, you may change the mouse settings to
use the left mouse button by the set mouse left command
(c.f. mouse functions ).
The default settings of Wit!P assume that you are using a 3 button mouse.
If you are using a 2-button mouse you should issue the command
Wit!P> set mouse 2Buttons
(c.f. mouse functions ).
If Wit!P GUI is started, you are ready to read
a molecule from a PDB file. Otherwise, you will first have to find
out why the witnotp command failed.
