5 <p>Selecting this option brings up a window asking you to select a threshold.

6 If the percentage identity between two sequences (based on the
\r
7 current alignment) exceeds this value one of the
\r
8 sequences (the shorter) is discarded. The redundancy calculation is done when
\r
9 the Apply button is pressed, and the undo button recovers the
\r
10 original set or any previously calculated subset. The detection of
\r
11 redundant sequences involves a pairwise comparison of all the
\r
12 sequences, so you may have to wait a few moments when applying this to
\r
13 large sequence sets.</p>
