<p><strong>Removing redundancy</strong></p>\r
<p>Selecting this option brings up a window asking you to select a threshold.\r
- If the percentage identity between two sequences (based on the\r
- current alignment) exceeds this value one of the\r
+ If the percentage identity between two sequences exceeds this value one of the\r
sequences (the shorter) is discarded. The redundancy calculation is done when\r
- the Apply button is pressed, and the undo button recovers the\r
- original set or any previously calculated subset. The detection of\r
- redundant sequences involves a pairwise comparison of all the\r
- sequences, so you may have to wait a few moments when applying this to\r
- large sequence sets.</p>\r
+ the Apply button is pressed. For large numbers of sequences this can take a\r
