Pop-up Menus of MarvinSketch

There are four pop-up menus (also called context or right-click menus) available in MarvinSketch:

These popup menus do not require the corresponding atom, bond or object to be selected, however there are some additional menu elements that appear only when they are selected.

Atom Pop-up Menu

The Atom pop-up menu appears when you right-click on an atom on the canvas. It contains options for atom-specific activities.

Menu Item

Description

Stereo

Assigns reaction stereo labels or enhanced stereo labels to atoms. See the Enhanced stereo specification for details.

Charge

Applies a charge between [-128,128] to the atom. Marvin will let you set any of these values on any atom, highlighting the Valence Errors in red upon completion. In other words, Marvin will allow you to set a charge of -5 on hydrogen, despite the fact that this is chemically impossible.

Radical

Sets the selected atom as a radical. You can select the type of radical - monovalent, divalent, divalent singlet, divalent triplet, trivalent, trivalent doublet, trivalent quartet. The Off option removes the radical designation.

Isotope

The Isotope submenu contains a list of the isotopes of the selected element, dynamically generated based on the selected atom. Select an isotope to set or change the isotope number or choose Off to reset the default atom type (no isotope).

Map

Set map labels/identifiers on the selected atoms that do not change while altering the molecule. They are useful when dealing with reactions, and can be saved in SMILES and MDL formats.

R-group

Change the selected atom to an R-group label. R-groups symbolize alternative substituents.

Link Node

Link node specifies rings or chains of variable size.

Attachment Point

If the selected atom is part of a group (R-group definition or abbreviated group), you can specify an attachment point.

Delete

Removes the atom from the molecule.

Add Branch

Adds a new bond with implicit hydrogen to the selected atom. This option is disabled for atoms that can have no more bonds.

Format

Change atom drawing properties.

Add To My Templates

Adds the selected structure to the "My Templates" group that appears in the Template Library and on the Advanced Templates Toolbar.

Bond Pop-up Menu

The bond pop-up menu appears when you right-click on a bond within the molecule. It allows you to make a number of changes to the selected bond.

Menu Item

Submenu Items

Description

Type

Single

Changes the selected bond type to Single.

Double

Changes the selected bond type to Double.

Triple

Changes the selected bond type to Triple.

Aromatic

Changes the selected bond type to Aromatic.

Query bond types

Changes the selected bond to a bond type (Single Up, Single Down, Single Up or Down, Double Cis or Trans, Double C/T or Unspec, Single or Double, Single or Aromatic, Double or Aromatic, Any) for use in a query.

Attributes

Stereo Search

Uses stereoconfiguration of specified double bond when this molecule is used as a query.

In Ring

Sets a bond property so that when the molecule is used as a query, the specified bond must be in a ring to score a hit.

In Chain

Sets a bond property so that when the molecule is used as a query, the specified bond must be in a chain to score a hit.

Reacting Center

See Reacting center bond query feature description.

Align

Vertical

Orients the bond vertically.

Horizontal

Orients the bond horizontally.

Delete

Removes the bond from the molecule.

Format

Change bond drawing properties.

Add To My Templates

Adds the selected structure to the "My Templates" group that appears in the Template Library and on the Advanced Templates Toolbar.

Object Pop-up Menu

This menu appears when the context is a graphical object like Text, Bracket, or other Graphics.


Menu Item

Description

Bring to Front

Brings the selected object in front of all others.

Send to Back

Places the selected object behind all others.

Delete

Removes the object from the canvas.

Format

Change object drawing properties.

Add To My Templates

Adds the selected structure to the "My Templates" group that appears in the Template Library and on the Advanced Templates Toolbar.

Edit Pop-up Menu

The Edit pop-up menu appears when you right-click on open canvas space (i.e. not on an atom, bond or object ). Edit pop-up menu items include:

Menu Item Description
Add/Remove Explicit Hydrogens Switches explicit H atoms to implicit ones and vica versa. Explicit hydrogens are displayed with atoms joining its neighbor while implicit hydrogens are displayed by atom symbols only.
Add/Remove Map Atoms Adding atom maps is an automatic assignment of map numbers to all selected atoms of a reaction by using the automapper tool.
Add/Remove Data Attach/Remove data like stoichiometry coefficient to the molecule.
Add/Remove Absolute Stereo (CHIRAL) Sets/Removes chiral flag for the molecule.
Add Multi-Center Add 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.
Edit Data Changes a previously attached data like stoichiometry coefficient of the molecule.
Link Node Specifies query structures containing rings or chains of variable size.
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.
Merge Reaction Fragments Merge the selected fragments to a reactant, product or agent.
Split Reaction Fragments Split the previously merged reaction fragments.

Format

Change atom and bond drawing properties.

Add To My Templates

Adds the selected structure to the "My Templates" group that appears in the Template Library and on the Advanced Templates Toolbar.

Pop-up elements upon Selection

Menu Item

Description

Recent

The Recent submenu contains a list of atoms and templates previously placed on the canvas. It does not include recently used bonds. You can change the drawing object by selecting one of the items in this list.

Cut

Removes and copies the selection to the clipboard.

Copy

Copies the selection to the clipboard.

Copy as SMILES

Copies the selection to the clipboard in SMILES format.

Paste

Inserts the contents of the clipboard at the location of the cursor, without replacing selection.

Select All

Selects the structure being on the canvas including all fragments and graphical objects.

Create Group

Creates an abbreviated Group from the selected substructure. See the S-groups section for more information on creating and using Groups.

Flip

Flips the structure on the canvas. The submenu allows you to choose horizontally or vertically.

Mirror

Flips the object horizontally, inverting tetrahedral stereochemistry. The submenu allows you to choose horizontally or vertically.
