By default, MarvinSketch displays all the R-group definitions that belong to a scaffold.
Sometimes it is very practical to hide the R-group definitions because they take up too much place from the display and we would like to emphasize the scaffold.
The result of switching off the R-group definitions can be seen in the picture below.
The code below is taken from
SketchParams.java, where the R-group definitions are hidden using the
setParams method of the
msketchPane. setParams (ParameterConstants.R_GROUPS_VISIBLE+ "=false" );
