Alignment Window Menus
- File
- Fetch Sequence
Shows a dialog window in which you can select known ids from Uniprot,
EMBL, EMBLCDS or PDB database using Web Services provided by the European
Bioinformatics Institute. See Sequence
Fetcher.
- Save As
Save the alignment to local file. A file selection window
will open, use the "Files of type:" selection box to determine
which alignment format to save as.
- Export
Creates an alignment graphic with the current annotation, alignment background
colours and group colours. If the alignment is wrapped, the output will also be wrapped
and will have the same visible residue width as the open alignment.
- Output to Textbox
The alignment will be displayed in plain text in a new window
which you can "Copy and Paste" using the pull down menu, or
your standard operating system copy and paste keys.
Select the format of the text by selecting one of the following menu items.
- FASTA
- MSF
- CLUSTAL
- BLC
- PIR
- PFAM
- Print
Jalview will print the alignment using the current fonts
and colours of your alignment. If the alignment has annotations visible,
these will be printed below the alignment. If the alignment is wrapped
the number of residues per line of your alignment will depend on the paper
width or your alignment window width, whichever is the smaller.
- Load Associated Tree
Jalview can view trees stored in the Newick
file format, and associate them with the alignment. Note: the ids of the
tree file and your alignment MUST be the same.
- Load Features / Annotations
Load files describing precalculated sequence
features or alignment
annotations.
- Close
Close the alignment window. Make sure you have saved your
alignment before you close - either as a Jalview project or by using the
Save As menu.
- Edit
- Undo
This will undo any edits you make to the alignment. This applies to insertion
or deletion of gaps, cutting residues or sequences from the alignment
or pasting sequences to the current alignment or sorting the alignment.
NOTE: It DOES NOT undo colour changes, adjustments to
group sizes, or changes to the annotation panel.
- Redo
Any actions which you undo can be redone using redo.
- Cut
This will make a copy of the currently selected residues
before removing them from your alignment. Click on a sequence name if
you wish to select a whole sequence.
Use <CTRL> and X (<APPLE> and X on MacOSX) to cut.
- Copy
Copies the currently selected residues to the system clipboard - you
can also do this by pressing <CTRL> and C (<APPLE> and C on
MacOSX).
If you try to paste the clipboard contents to a text editor, you will
see the format of the copied residues FASTA.
- Paste
- To New Alignment
A new alignment window will be created from sequences
previously copied or cut to the system clipboard.
Use <CTRL> and V(<APPLE> and V on MacOSX) to paste.
- Add To This Alignment
Copied sequences from another alignment window can be
added to the current Jalview alignment.
- Delete
This will delete the currently selected residues without
copying them to the clipboard. Like the other edit operations, this can
be undone with Undo.
- Select All
Selects all the sequences and residues in the alignment.
Use <CTRL> and A (<APPLE> and A on a MacOSX) to select all.
- Deselect All
Removes the current selection box (red dashed box) from the
alignment window. All selected sequences, residues and marked columns
will be deselected.
Use <ESCAPE> to deselect all.
- Invert Selection
Any sequence ids currently not selected will replace the
current selection.
- Undefine Groups
The alignment will be reset with no defined groups.
WARNING: This cannot be undone.
- Remove Left
If the alignment has marked columns, the alignment will be
trimmed to the left of the leftmost marked column. To mark a column, mouse
click the scale bar above the alignment. Click again to unmark a column,
or select "Deselect All" to deselect all columns.
- Remove Right
If the alignment has marked columns, the alignment will be
trimmed to the left of the leftmost marked column. To mark a column, mouse
click the scale bar above the alignment. Click again to unmark a column,
or select "Deselect All" to deselect all columns.
- Remove Empty Columns
All columns which only contain gap characters ("-",
".") will be deleted.
You may set the default gap character in preferences.
- Remove All Gaps
Gap characters ("-", ".") will be deleted from
the selected area of the alignment. If no selection is made, ALL the gaps
in the alignment will be removed.
You may set the default gap character in preferences.
- Remove Redundancy
Selecting this option brings up a window asking you to select
a threshold. If the percentage identity between any two sequences (under
the current alignment) exceeds this value then one of the sequences (the
shorter) is discarded. Press the "Apply" button to remove redundant
sequences. The "Undo" button will undo the last redundancy deletion.
- Pad Gaps
When selected, the alignment will be kept at minimal
width (so there no empty columns before or after the first or last aligned
residue) and all sequences will be padded with gap characters to
the before and after their terminating residues.
This switch is useful when making a tree using unaligned
sequences and when working with alignment analysis programs which
require 'properly aligned sequences' to be all the same length.
You may set the default for Pad Gaps in the preferences.
Search
- Find
Select this to search
for residues, sequence name or residue position within the
alignment and create new sequence features from the queries.
View
- Font
Change the font of the display from the "Choose Font"
dialog box, which is shown when this item is selected.
- Smooth Fonts
If selected, the alignment will be drawn with anti-aliasing on which looks
better, but performace is reduced.
- Wrap
When ticked, the alignment display is "wrapped"
to the width of the alignment window. This is useful if your alignment
has only a few sequences to view its full width at once.
Options are available to show the residue numbering at the start and/or
end of an alignment as well as showing the alignment position above each
sequence row.
NOTE: When in wrapped alignment view, the alignment cannot
be edited or have regions selected on it.
- Show Full Sequence ID
If this box is selected the sequence name will have the start
and end position of the sequence appended to the name, in the format NAME/START-END
- Boxes
If this is selected the background of a residue will be coloured using
the selected background colour. Useful if used in conjunction with "Colour
Text."
- Text
If this is selected the residues will be displayed using
the standard 1 character amino acid alphabet.
- Colour Text
If this is selected the residues will be coloured according
to the background colour associated with that residue. The colour is slightly
darker than background so the amino acid symbol remains visible.
- Show Gaps
When this is selected, gap characters will be displayed as
"." or "-". If unselected, then gap characters will
appear as blank spaces.
You may set the default gap character in preferences.
- Show Annotations
If this is selected the "Annotation Panel" will
be displayed below the alignment. The default setting is to display the
conservation calculation, quality calculation and consensus values as
bar charts.
- Fetch Sequence Features
If the sequence names are Swissprot entries Jalview will
use the names to retrieve sequence
features from the EBI. Features which are 1 residue in length are
coloured red, sequences longer than 1 residue are coloured blue. Move
the mouse over a coloured feature to display the details of the feature.
Note: The retrieved information will update the sequence start and end
labels if they are incorrect.
- Show Sequence Features
Show or
hide sequence features on this alignment.
- Seqence Feature Settings...
Control the colour and display of sequence features on the
alignment. See Sequence Feature Settings.
- Overview Window
A scaled version of the alignment will be displayed in a
small window. A red box will indicate the currently visible area of the
alignment. Move the visible region using the mouse.
Colour
- Apply Colour To All Groups
If this is selected, any changes made to the background colour
will be applied to all currently defined groups.
- Colour Scheme options: None, ClustalX, Blosum62 Score, Percentage
Identity, Zappo, Taylor, Hydrophobicity, Helix Propensity, Strand Propensity,
Turn Propensity, Buried Index, Nucleotide, User Defined
See colours for
a description of all colour schemes.
- By Conservation
See Colouring
by Conservation.
- Modify Conservation Threshold
Use this to display the conservation threshold slider window.
Useful if the window has been closed, or if the 'by conservation' option
appears to be doing nothing!
- Above Identity Threshold
See Above Percentage
Identity.
- Modify Identity Threshold
Use this to set the threshold value for colouring above Identity.
Useful if the window has been closed.
- By Annotation
Colours the alignment on a per-column value from a specified annotation.
See Annotation Colouring.
Calculate
- Sort
- by ID
This will sort the sequences according to sequence name. If the sort
is repeated, the order of the sorted sequences will be inverted.
- by Group
This will sort the sequences according to sequence name.
If the sort is repeated, the order of the sorted sequences will be
inverted.
- by Pairwise Identity
This will sort the selected sequences by their percentage
identity to the consensus sequence. The most similar sequence is put
at the top.
- The Sort menu will
have some additional options if you have just done a multiple alignment
calculation, or opened a tree viewer window.
- Calculate Tree
Functions for calculating trees on the alignment or the currently
selected region. See calculating trees.
- Average Distance Using % Identity
- Neighbour Joining Using % Identity
- Average Distance Using Blosum62
- Neighbour Joining Using Blosum62
- Pairwise Alignments
Applies Smith and Waterman algorithm to selected sequences. See pairwise
alignments.
- Principal Component Analysis
Shows a spatial clustering of the sequences based on the BLOSUM62
scores in the alignment. See Principal
Component Analysis.
- Translate cDNA
If you are viewing a cDNA alignment a very simple translation service
is available. The translation ignores all gaps in the cDNA sequences.
Web Service
Selecting one of the following menu items starts a remote service
on compute facilities at the University of Dundee. You need a continuous network
connection in order to use these services through Jalview.
- Alignment
- ClustalW Multiple Sequence Alignment
Submits all, or just the currently selected sequences for alignment
with clustal W.
- ClustalW Multiple Sequence Alignment Realign
Submits the alignment or currently selected region for re-alignment
with clustal W. Use this if you have added some new sequences to an
existing alignment.
- Muscle Multiple Protein Sequence Alignment
Submits all, or jut the currently selected sequences for alignment
using Muscle. Do not use this if you are working with nucleic acid
sequences.
- Secondary Structure Prediction
- JPred Secondary Structure Prediction
Secondary structure prediction by network consensus. The behaviour
of this calculation depends on the current selection:
- If nothing is selected, and the displayed sequences appear to
be aligned, then a JNet prediction will be run for the first sequence
in the alignment, using the current alignment. Otherwise the first
sequence will be submitted for prediction.
- If just one sequence (or a region on one sequence) has been
selected, it will be submitted to the automatic JNet prediction server
for homolog detection and prediction.
- If a set of sequences are selected, and they appear to be aligned,
then the alignment will be used for a Jnet prediction on the first
sequence selected in the set (that is, the one that was first clicked
on).
