TITLE           Complement Reverse

OCCURRENCE      ARB_NT/ARB_EDIT/EDIT/Complement

DESCRIPTION     Complements and/or reverses (part of) sequences. This is helpful
                if sequences were entered the wrong way round or if
                potential higher order structure elements should be studied.

                Select a sequence by positioning the cursor on its name and
                        pressing the left mouse button.

                Choose the 'Complement' item from the 'ARB_EDIT/EDIT' menu to
                        display the 'COMPLEMENT and REVERSE' window.

                Define whether the sequence should be reversed, complemented or
                        both by choosing from the menu displayed after pressing 
                        the <COMPLEMENT/REVERSE> button.

                Define whether the position of gap symbols should be maintained
                        (default) or the gaps should be removed (press the
                        <remove> button).

                Type left and right positions to the respective subwindows if
                        part of the sequence should be complemented and/or
                        reversed. In this case, press the <SEQUENCE PART>
                        button.

                Press <REST SEQUENCE> or <REST EDITOR> to complement or
                        reverse the sequence from the current cursor position to
                        the (right) end of the sequence or the (right) end of
                        the last (bottom) edited sequence, respectively.

                Press <SEQUENCE> or <ALL> to complement the selected sequence or
                        all edited sequences (independent of the
                        cursor position).
                                
NOTES           None    

EXAMPLES        None

WARNINGS        !!! It is recommended to copy the sequence data before
                performing the operations. Currently there is no way to prevent
                the export of the modified sequences to the database. Saving
                the database means saving the complemented sequences. !!!!

                Deleting gaps takes a lot of time.
