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>
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 Description (optional) Values
+ The GRAPH_TYPE field, which appears first, defines the + appearance of the annotation row when rendered by Jalview. The next + field is the row label for the annotation. This may be + followed by a description for the row, which is shown in a + tooltip when the user mouses over the annotation row's label. Since + Jalview 2.7, the description field may also contain html in the same + way as a sequence feature's label, + providing the html is enclosed in an <html/> tag. + +
The final Values + field contains a series of "|" separated value fields. Each + value field is itself a comma separated list of fields of a particular + type defined by the annotation row's GRAPH_TYPE. The allowed values of + GRAPH_TYPE and the format of their respective value fields (with the + trailing "|" symbol) are shown below: + +
Color strings can be embedded in a value field by enclosing an RGB triplet in square brackets to colour that position in an annotation row. +
+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+ +
Similarly, since Jalview 2.5, group associated annotation can be defined by preceding the row definitions with the line: +
GROUP_REF group_name+Group association is turned off for subsequent annotation rows by: +
GROUP_REF ALIGNMENT+ +
LINE_GRAPH type annotations can be given a colour +(specified as 24 bit RGB triplet in hexadecimal or comma separated +values), combined onto the same vertical axis, and have ordinate lines +(horizontal lines at a particular vertical axis value) using the +following commands (respectively): +
COLOUR graph_name colour +COMBINE graph_1_name graph_2_name +GRAPHLINE graph_name value label colour ++ +
The visual display properties for a set of annotation rows can be modified using the following tab-delimited line:
+ROWPROPERTIES Row label centrelabs=true( or false) showalllabs=true(default is false) scaletofit=true (default is false)+
This sets the visual display properties according to the given values for all the annotation rows with labels matching Row label. The properties mostly affect the display of multi-character column labels, and are as follows: +
Groups of sequences can be defined using the tab delimited line
+SEQUENCE_GROUP Group_Name Group_Start Group_End Sequences+
The sequences can be defined by alignment index and a range of sequences can + be defined in a comma delimited field such as
+2-5,8-15,20,22
+Enter * to select all groups.
+Note: If the alignment indices are not known, enter -1, followed by a tab and then a tab delimited list +specifying the sequence ids.
+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.
+The group can (optionally) be assigned various visualisation properties via + another tab delimited line thus:
+PROPERTIES Group_name tab_delimited_key_value_pairs ++
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:
+description=Text
+ colour=Helix Propensity
+ pidThreshold=0
+ consThreshold=0
+ outlineColour=red
+ displayBoxes=true
+ displayText=false
+ colourText=false
+ textCol1=black
+ textCol2=black
+ textColThreshold=0
+ idColour=ff3322
+
+ showunconserved=false
+
