+<p> <em>Colouring above a percentage identity threshold</em></p>\r
+<p> Selecting this option causes the colour scheme to be applied to only those \r
+ residues that occur in that column more than a certain percentage of the time. \r
+ For instance selecting the threshold to be 100 will only colour those columns \r
+ with 100 % identity. This threshold option can be applied to the Zappo, Taylor, \r
+ Hydrophobicity and User colour schemes. </p>\r
