</strong><em>When selected, the alignment will be kept at minimal\r
- width (no empty columns before or after the first or last aligned\r
- residue). This is useful when making a tree using unaligned\r
+ width (so there no empty columns before or after the first or last aligned\r
+ residue) and all sequences will be padded with gap characters to\r
+ the before and after their terminating residues.<br>\r
+ This switch is useful when making a tree using unaligned\r
sequences and when working with alignment analysis programs which\r
require 'properly aligned sequences' to be all the same length.<br>\r
