Hi,
I am using Jalview (or trying to!) to add sequence features to my multiple alignment.
When I right-click a residue selection, I can choose to “create” a new sequence feature.
However, how can I apply an existing sequence feature without creating it all over again?
So, purely for example, let’s say that I have an alignment with 40 homologous enzymes. In my first sequence, I want to mark helix-hairpin-helix motifs manually as a sequence feature with a specific colour:
I select the appropriate range in the first sequence, right-click and add a new “helix hairpin helix” feature in purple.
Then I change to a different labelling task and decide that I want to label the active site as a sequence feature in this first sequence. I duly do so as before.
Now, I decide that I want to continue with the remaining thirty-nine sequences. I want to select specific ranges individually in each sequence and apply the helix-hairpin-helix feature again. However, I cannot find how to apply the existing feature - it has to be recreated and the name and colour has to be matched. Surely there is a list somewhere of features already applied to the project with a control to re-apply that feature to a new sequence segment?
Again, am I missing something? 
Thank you
Michael
