TITLE		Define Helix Symbols

OCCURRENCE	ARB_EDIT4/Properties/Helix settings

DESCRIPTION

        Different base pairs in helix regions can be indicated by user-definable symbols.
        This window allows you to change the mapping between base pairs and displayed
        symbols.

SECTION Configuration

                Show helix: Toggle display of helix symbols

                Pair definitions. Each line contains two textfields:

                     The left textfield contains one or more base-pairs. Each base
                     pair contains two characters (bases, gaps-characters, ...).
                     Base-pairs are separated by spaces (' '). 

                     The right textfield contains the helix symbol used for each
                     of the specified pairs.

NOTES

        - Pairs are not case-sensitive
        - If a pair is not defined in any line, the symbol given
          behind 'Default' is used. 

SECTION Missing
