The SKC format of ISIS/Draw is imported and exported by Marvin. Most properties of atoms, bonds, groups (R-group and S-groups), query structures and reactions are supported.
Export and Import
The main features:
Chemical structures (atom properties, labels, bond types)
Atom and bond query properties
Graphical objects (rectangle, ellipse, graphical brackets)
Some graphical object or objects properties are not available in Marvin (e.g. graphics arc, line style of graphical objects and underlined text).
Graphical brackets are not supported by ISIS/Draw, thus all brackets are imported as S-groups.
