Align many sequences to same reference
[Menu-bar>Align] With this dialog a reference protein can be aligned to many other
proteins producing a pair-alignments for each protein.
On pressing 
the sequence alignments appear in the preview.
Inferred into the working alignment
Sequence alignments can be applied to the working sequence alignment.
Only the gaps of the reference protein are changed in the working alignment.
The other proteins are not changed.
Highlighting of the match:
Table rows can be selected using the 
toggles.
The matches of selected rows are highlighted in the alignment.
Limitations:
The induction of gaps from the calculated sequence alignment into the working
sequence alignment may fail because only the residue positions of the
reference protein but not of the other sequences are changed by
this procedure.
Therefore, it might not find sufficient white space in the multiple sequence
alignment.
