+<p>A features file is a simple ASCII text file, where each line\r
+contains tab separated text fields. <strong>No comments are\r
+allowed</strong>.</p>\r
+<p>The first set of lines contain type definitions:<strong>\r
+<pre><em>Feature label</em>	<em>Feature Colour</em></pre>\r
+</strong>A feature type has a text label, and a colour (specified as a\r
+red,green,blue 24 bit triplet either in hexadecimal (eg. 00ff00) or as comma\r
+separated numbers (ranging from 0 to 255)).\r
+<p>The remaining lines in the file are the sequence annotation\r
+definitions, where the now defined features are attached to regions on\r
+particular sequences, optionally with some descriptive text (displayed\r
+in a tooltip when the mouse is near the feature on that sequence). There are two alternate ways of referring to a\r
+sequence, either by its text ID, or its index in an associated\r
+alignment.<pre>\r
+<em>description</em>	<em>sequenceId</em>	<em>sequenceIndex</em>	<em>start</em>	<em>end</em>	<em>featureType</em></pre>Normally,\r
+sequence features are associated with sequences rather than\r
+alignments, and the sequenceIndex field is given as "-1". In\r
+order to specify a sequence by its index in a particular alignment, the\r
+sequenceId should be given as "ID_NOT_SPECIFIED", otherwise the\r
+sequenceId field will be used in preference to the sequenceIndex field.</p><p>\r
+Feature annotations can be collected into named groups by prefixing\r
+definitions with lines of the\r
+form:<strong><pre>startgroup	groupname</pre></strong>.. and\r
+subsequently post-fixing the group\r
+with:<strong><pre>endgroup	groupname</pre></strong>Feature grouping\r
+was introduced in version 2.08, and used to control whether a set of features\r
+are either hidden or shown together in the <a href="seqfeatures.html">sequence Feature settings\r
+dialog box</a>.</p>\r
