This routine can transfer sequences from one alignment to another.
Parameters are the name of the source and destination alignment.
If these alignments are of different length, the routine aborts. You can then choose in a sequences selection box which ones you want to transfer. If the sequence exists in the destination alignment, it will be overwritten by the sequence in the source alignment. Sequences not present in the destination alignment are appended to it. The program will not pop up an sequences selection box .
