Copy annotations to other sequences
Annotations on one sequence can be transferred to other sequences in the alignment:
right-click the annotation | Copy Annotation to other Sequences
This will display a dialog listing all the sequences in the alignment. Next to each sequence is a checkbox which is used for selecting which sequences, the annotation should be copied to. Click Copy to copy the annotation.
If you wish to copy all annotations on the sequence, click the Copy All Annotations to other Sequences.
