-<p><em>Clustal X</em></p>\r
- <p>Clustal X is a graphical interface for the ClustalW multiple sequence alignment\r
- program. Sequences can be coloured either by assigning a colour to specific\r
- residues, or on the basis of an alignment consensus. The residues in each\r
- column are coloured according to the consensus character assigned to that column.\r
- In this way, you can choose to highlight, for example, conserved hydrophilic\r
- or hydrophobic positions in the alignment. </p>\r
+<p><em>Clustal X Colour Scheme</em></p>\r
+ <p>This is an emulation of the default colourscheme used for alignments in
+ Clustal X, a graphical interface for the ClustalW multiple sequence alignment\r
+ program. Each residue in the alignment is assigned a colour if the
+ amino acid profile of the alignment at that position
+ meets some minimum criteria specific for the residue type.</p>
+ <p>The table below gives these criteria as clauses: {+X%,xx,y},
+ where X is the minimum percentage presence for any of the xx (or y) residue types.</p>\r
