When invoked with valid data (e.g. platon squeeze.res) a menu offering a table of mouse-click selectable program functions and an option menu is brought up, otherwise the user is given the option to supply data interactively from the keyboard.
When PLATON doesn't succeed to open an X-window, it automatically switches to interactive input from the keyboard with TEK4010 graphics (useful when PLATON is run using a Tektronix emulator over a modem line; the author uses PC-PLOT for this).
A possible reasons for not bringing up the opening window can be a failure to connect to the X-Window server (check the xhost setting at the server side and the DISPLAY variable at the client side.
Keyboard input (i.e. no menu's and no graphical user interface) as default is choosen when PLATON is invoked with the '-o' option.
The X-Window area is devided in four subwindows.
Left-button clicks with the mouse on menu items invoke calculations or parameter settings.
Right-button clicks on menu items generate a help/info page on the associated items (assuming that Netscape is available) and a manual for the yellow menu headers (e.g. a manual on the available techniques for correction for absorption).
Netscape is started when not already open. The PLATON main menu carries a toggle to switch off the start-up of Netscape.
Input data and instructions may be entered with the keyboard and/or mouse-clicks on menu items.
In the MENU mode, input can be given either from the keyboard (useful for the more complex instructions as detailed in the PLATON MANUAL or PLUTON MANUAL) or via mouse clicks.
A left-button click on the ORTEP/ADP button will bring up an ORTEP presentation with associated ORTEP menu as shown in Fig. 2
A corresponding PLUTON style plot ( Fig. 3 ) can be generated by clicking on 'PLUTON-ELD' in the ORTEP-menu.
Fig. 4 is generated after clicking OFF the 'decoration' & 'labelling' followed by clicking on 'CPK'. A Postscript copy is generated by clicking on the 'EPS' button.
Clicking on POV will bring up a ray-traced POVRAY image Fig.5.
Clicking on 'END' results in a return to the PLATON main window. An additional click on END terminates to tour.
