3.1. Role of each part
The window (called Main Window ) that appears after starting Winmostar has the configuration shown below.
In the title of Main Window, the name of the file currently being edited, the license and version of Winmostar in use are displayed.
- Toolbar
Here you can also select commonly used functions in the main menu. You can check the role of each button by overlaying the pointer. In addition, only the following functions perform special operations.
Depending on the solver selected in the Solver pull-down menu
(default is MOPAC) in the first row of the upper toolbar, the role of buttons such as Configure, Run will change.
Depending on the element selected in the Select element used in editing operations pull-down menu, the behavior of Add Atom and Change Element buttons beside it will change.
- Viewport
The molecular structure currently being edited is displayed. By default, the structure where carbon atom (green) and hydrogen atom (yellow) are bonded is displayed.If the menu is checked, detailed information will be displayed at the top and bottom.Red circle indicates atom selection marker.In group selection state, atoms are surrounded by blue circles.You can toggle the number displayed on the side of each atom and the type of charge value from the menu.The color scheme can be changed from the .
- Keyword Editor
The contents set in the configuration window of each solver are displayed. By default MOPAC settings are displayed.
- Coordinate Viewer
The coordinates of each atom of the molecular structure displayed in Viewport are displayed.You can switch the display format and output format on the upper tab.By default Z-Matrix is selected.In a state where no group is selected, the line selected in Coordinate Viewer matches the atom with the marker (red circle).Group selection (blue circle) can be done by selecting multiple lines by Ctrl+left click or Shift+left click.
- Coordinate Editor
You can enter the coordinates (Z-Matrix or XYZ format) of the atom with the marker (red circle) and the optimization flags.
- Keyword Editor (secondary)
It is basically the same as Keyword Editor, but the contents entered here will appear after the coordinates in the input file of the solver. It is used only for some solvers such as GAMESS and Quantum ESPRESSO.
