-\subsection{Creating User Defined Annotation}
-
-Annotations are properties that apply to the alignment as a whole and are visualized on rows in the annotation panel.
-To create a new annotation row, right click on the annotation label panel and select the {\sl Add New Row} menu option (Figure \ref{newannotrow}). A dialogue box appears. Enter the label to use for this row and a new row will appear.

-\label{newannotrow}
-\end{center}
-\end{figure}
-
-To create a new annotation, first select all the positions to be annotated on the appropriate row. Right-clicking on this selection brings up the context menu which allows the insertion of graphics for secondary structure ({\sl Helix} or {\sl Sheet}), text {\sl Label} and the colour in which to present the annotation (Figure \ref{newannot}). On selecting {\sl Label} a dialogue box will appear, requesting the text to place at that position. After the text is entered, the selection can be removed and the annotation becomes clearly visible\footnote{When annotating a block of positions, the text can be partly obscured by the selection highlight. Pressing the [ESC] key clears the selection and the label is then visible.}. Annotations can be coloured or deleted as desired.
