How to put a "+" sign onto the canvas:
Select the Reaction tool, then left-click onto the canvas where you would like to place the "+" sign.
If you select the reactant or the product side with the Selection tool and then press the Reaction tool button, the "+" sign(s) will be added automatically between each reactant or product molecule.
How to put an arrow onto the canvas:
Select the Reaction tool, then drag with it on the canvas where you would like to place the arrow. During the dragging a grey feedback shows the future position of the newly forming arrow. Release the button to create the arrow.
If it is necessary the length and the direction of the arrow can be changed afterwards.
Reaction export - Technical details
* Please note that the conversion of the structure to a reaction file happens on server side and requires the reaction converter Web Service to be available.
The Reaction operators are movable by dragging them on the canvas with active Selection tool.
How to delete reaction operators
You can delete reaction operators by clicking on them with active Delete tool, or by selecting them, then pushing the Delete button.
Clicking on the middle of the arrows when the Smart reaction tool is active deletes the arrow.
Merged agents represent a special grouping inside Marvin JS, which gives you the opportunity to handle structures together as one molecule in mrv format. This could be important when you need to visually indicate that separated structures belong together (for example salts) or if you need to use the mrv file in other softwares for example search.
Display of Merged agents
On hover squared brackets appear around the structures, and bonds and atoms in the group are indicated in grey.
Merged group is automatically removed if only one structural part remains in it, or if the group is moved to reactant or product position.
The grouping can be also removed, with Context menu Unmerge Agent(s) option.
