<p>You can associate an annotation with a sequence by preceding its
-definition with the line: <strong><pre>SEQUENCE_REF	<em>seq_name</em>	<em>[startIndex]</em></pre></strong>
+definition with the line:
+<pre>SEQUENCE_REF	<em>seq_name</em>	<em>[startIndex]</em></pre>
All Annotations defined after a SEQUENCE_REF command will then be
associated with that sequence, and the first field in the Value field
list will (optionally) be placed at the <em>startIndex</em>'th column.</p>
+<ul><em>New in Jalview 2.4</em>: the tooltip displayed when the mouse is moved over the row
+label for sequence associated annotation gives the associated

<p><em>LINE_GRAPH</em> type annotations can be given a colour

values), combined onto the same vertical axis, and have ordinate lines
(horizontal lines at a particular vertical axis value) using the

+<h3><font face="Arial, Helvetica, sans-serif">(Since Jalview 2.2.1) SEQUENCE_GROUP</font></h3>
+<p>Groups of sequences can be defined using the tab delimited line</p>
+<pre>SEQUENCE_GROUP Group_Name Group_Start Group_End Sequences</pre>
+<p>The sequences can be defined by alignment index and a range of sequences can
+ be defined in a comma delimited field such as</p>
+<p>2-5,8-15,20,22</p>
+<p>Enter * to select all groups. </p>
+<p>If the alignment indices are not known, enter -1 then a tab delimited list
+ of sequence ids. </p>
+<p>If the SEQUENCE_REF has been defined, the group_start and group_end will be
+ relative to the sequence residue numbering, otherwise the group_start and group_end
+ will be the alignment column indices. </p>
+<p>The group can (optionally) be assigned various visualisation properties via
+ another tab delimited line thus:</p>
+<pre>PROPERTIES Group_name tab_delimited_key_value_pairs
+</pre>
+<p>The key_value_pairs allow you to define a description and to colour the group
+ in various ways. All, none or some of the following values could be used for
+ a group:</p>
+<p>description=Text <br>
+ colour=Helix Propensity<br>
+ pidThreshold=0<br>
+ consThreshold=0<br>
+ outlineColour=red <br>
+ displayBoxes=true<br>
+ displayText=false<br>
+ colourText=false<br>
+ textCol1=black<br>
+ textCol2=black<br>
+ textColThreshold=0<br>
+ idColour=ff3322</p>
+<em>New Features in 2.4:</em><ul><li>if the <strong>idColour</strong> property
+is given without specifying a colour scheme with the <strong>colour</strong>
+property, then the idColour will also be used to colour the sequence.</li>
+<li>the <strong>colour</strong> property can take either a colour scheme name,
+ or a single colour specification (either a colour name like 'red' or an RGB
+ triplet like 'ff0066'). If a single colour is specified, then the group
+ will be coloured with that colour.</li>
+</ul>
