Menus of MarvinSketch

The Menu Bar contains almost all commands that are available in MarvinSketch.
The main menus are groups of functionally similar commands shown in the following picture:

File Menu
The File menu contains the available file operations, such as New, Open, Save, Print, and Close. (Note that the unsigned Swing applets contain only a subset of these functions.)
Edit Menu
The Edit menu contains general clipboard operations like Copy and Paste, structure selecting and deleting commands, as well as Marvin-specific editing options.
View Menu
The View menu allows you to alter the way the molecule is displayed without modifying the structure file itself. You can change the molecule display type, background color, color scheme, error highlighting, etc.
See also: Structure Display Options.
The view menu also contains operations to change the graphical user interface.
Insert Menu
The Insert menu allows drawing structure templates, bonds, reaction arrows, graphics, text boxes, and more on the canvas. It is also possible to add a special text box containing the IUPAC Name of the structure.

Structure Menu

Clean 2D > Clean in 2D Calculates new 2D coordinates for the molecule.
Clean 2D > Hydrogenize Chiral Center Adds an explicit hydrogen atom to a chiral center having no terminal atoms when 2D cleaning is performed.
Clean 2D > Clean Wedge Bonds Arranges the wedge bonds of the molecule in 2D.
Clean 3D > Clean in 3D Calculates new 3D coordinates for the molecule. Clean3D builds up conformers of fragments from which the best, i.e. the lowest energy conformer is given back. The quality of the structures is measured by a simple energy function (Dreiding type molecular mechanics).
Clean 3D > Cleaning Method > Fine Build Fine Clean3D builds up conformers of fragments to find low energy conformer. Leaves failed fragments intact.
Clean 3D > Cleaning Method > Fine with Hydrogenize The build process always adds explicit Hydrogens to the structures which are removed if not present in the original molecule. This option prevents the removal of extra Hydrogen atoms, otherwise gives the same results than Fine build.
Clean 3D > Cleaning Method > Fast Build Fast clean, which if fails, performs fine clean. It accepts any generated structure, and it is the default behavior of the Clean3D function.
Clean 3D > Cleaning Method > Build or Optimize Builds 3D structure for non-3D molecules and just optimizes the 3D molecules with the Dreiding force field.
Clean 3D > Cleaning Method > Gradient Optimize Optimizes with the Dreiding force field using the actual structure as starting geometry.
Clean 3D > Display Stored Conformers Allows you to choose one of the possible conformer structures which were calculated via the Conformers plugin.
Add > Add Explicit Hydrogens Adds explicit H atoms instead of the current implicit ones. Explicit hydrogens are displayed with atoms joining its neighbor while implicit hydrogens are displayed by atom symbols only.
Add > Data Attaches data like stoichiometry coefficient to the molecule.
Add > Absolute Stereo (CHIRAL) Sets chiral flag for the molecule.
Add > Multi-Center Adds a multi-center attachment point representing a group of atoms.
Add > Position Variation Bond Create a variable point of attachment to represent a connection point to a group of atoms.
Remove > Remove Explicit Hydrogens Removes explicit H atoms and increases the number of implicit hydrogens.
Remove > Data Removes attached data from the molecule.
Remove > Absolute Stereo (CHIRAL) Removes the chiral flag of the molecule.

Reaction > Map Atoms Automatic assignment of map numbers to all selected atoms of a reaction by using the automapper tool.
Reaction > Mapping Method > Complete All atoms in the reaction are mapped.
Reaction > Mapping Method > Changing Only those atoms are mapped that have changing bond. Either the bond order changes, or new bond is created, or bond is deleted. Orphan and widow atoms are included.
Reaction > Mapping Method > Matching Maps all matching atoms in the reaction (Daylight style mapping). A reaction atom is called matching if it is not an orphan/widow atom: it exists on both sides of the reaction.
Reaction > Unmap Atoms Removes map numbers of the selected atoms.
Reaction > Merge Reactants Merges the selected fragments to a reactant, product or agent.
Reaction > Split to Reactants Splits the previously merged reaction fragments.
Attribute > R-Logic Allows setting additional R-group conditions such as occurrence, rest H and if-then expressions to R-groups in the R-logic dialog window.
