If you have copied a structure or fragment anywhere in the program or in a third party structure drawing tool, you can paste it to Structure Editor. If necessary, the structure can be changed or corrected and then returned to where it originated. This is especially useful for structure elucidation. For example, you can copy a structure from the Database Manager window, paste it to Structure Editor, make appropriate changes, and then move it back to Database Manager. If the spectrum and the structural proposal are not consistent, the process can be repeated.

To paste a structure to Structure Editor:

• Click the Paste button  in the Structure Editor.
• Or choose the Paste item from the Edit menu.

If you have copied a structure or fragment in a program other than Mass Frontier, you can only paste this structure if the external structure drawing software supports MOL format and this format is activated. The majority of structure drawing tools support MOL format and usually have this format activated by default. If you paste a structure from an external source it may sometimes appear larger in Mass Frontier than in the original software. If this should happen, you can simply make the structure smaller using the Resize tool.
