Alignment Annotations File Format
-
- Note: This format is primarily intended to be used for the applet, which does
- not have an XML parser and where file size must be kept to a minimum to reduce
- download time.
A precalculated annotations fiile can read onto an alignment from the command - line ("-annotations"), by drag and dropping the the annotations file - onto an alignment or by selecting from the File menu "Load Features / Annotations".
-The File is in tab delimited format. The file must have the line JALVIEW_ANNOTATION - as an identifier. Then a block of annotations are added in the form GRAPH_TYPE - Label Values
-GRAPH_TYPE can be either BAR_GRAPH, LINE_GRAPH or NO_GRAPH. The values are - per alignment column, separated by "|". Multiple content per column - can be separated with commas, Jalview will display the content if it interprates - the content as a text label, or secondary structure character (H or E)
-You can optionally associate an annotation with a sequence by adding a line - SEQUENCE_REFseq_namestartIndex All Annotations after a SEQUENCE_REF will be - associated with that sequence. Use SEQUENCE_REF ALIGNMENT to cancel the associtations.
-The visual graphs can be coloured or combined with other graphs, or have an - arbitrary line drawn at a certain value using the following lines.
-COLOUR<tab>graph name<tab>colour
- COMBINE<tab>graph 1 name<tab>graph 2 name
- GRAPHLINE<tab>graph name<tab>value<tab>label<tab>colour
An example Annotation file may look like this:
+The Alignment Annotations File
+Alignment annotations can be imported onto an alignment since + version 2.08 of Jalview, via an annotations file. It is a simple + ASCII text file consisting of tab + delimited records similar to the Sequence Features File, and + introduced primarily for use with the Jalview applet.
+Alignment annotations files are imported into Jalview in the
+following ways:
+
+ -annotations <Annotations filename>
Annotations File Format
+The File consists of lines containing an instruction followed by
+ tab delimited fields, and any lines starting with "#" are
+ ignored. The first non-commented out line of a valid Annotations file must begin with :JALVIEW_ANNOTATION
A row of annotation is added with a line like
+GRAPH_TYPE Label Values
+
You can associate an annotation with a sequence by preceding its
+ definition with the line:
+SEQUENCE_REF seq_name [startIndex]
+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 startIndex'th column.
Sequence associations
+ are turned off for subsequent annotation definitions by:
+SEQUENCE_REF ALIGNMENT
LINE_GRAPH type annotations can be given a colour,
+ combined onto the same vertical axis, and have abscissa (lines of
+ constant value - so they are horizontal) at particular
+ values using the following lines (respectively):
+COLOUR graph name colour
+COMBINE graph 1 name graph 2 name
+GRAPHLINE graph name value label colour
An example Annotation file is given below:
