Jalview is a multiple sequence alignment viewer, editor and analysis tool.

+It is designed to be platform independent (running on Mac, MS Windows, Linux
and any other platforms that support Java). Jalview is capable of editing and
analysing large alignments (thousands of sequences) with minimal degradation in
-performance, and able to show multiple integrated views of the alignment and
-other data. Jalview can read and write many common sequence formats including

Jalview to access online alignment and secondary structure prediction programs,

Sequences, alignments, trees, structures, features and alignment annotation may also be exchanged with the local filesystem. Multiple visualizations of an alignment may be worked on simultaneously, and the user interface provides a comprehensive set of controls for colouring and layout. Alignment views are dynamically linked with Jmol structure displays, a tree viewer and spatial cluster display, facilitating interactive exploration of the alignment's structure.

basic operation of Jalview and should be sufficient for those who want to
launch Jalview (Section \ref{startingjv}), open an alignment (Section
\ref{loadingseqs}), perform basic editing (Section
\ref{selectingandediting}), colouring (Section \ref{colours}), and produce
publication and presentation quality graphical output (Section \ref{layoutandoutput}).

\section{Navigation}
\label{jvnavigation}
The major features of the Jalview Desktop are illustrated in Figure \ref{anatomy}. The alignment window is the primary window for editing and visualization, and can contain several independent views of the alignment being worked with. The other windows (Trees, Structures, PCA plots, etc) are linked to a specific alignment view. Each area of the alignment window has a separate context menu accessed by clicking the right mouse button.
Jalview has two navigation and editing modes: {\bf normal mode}, where
editing and navigation is performed using the mouse, and {\bf cursor mode}
where editing and navigation are performed using the keyboard. The {\bf F2 key}
- is used to switch between these two modes. With a Mac as the F2 is

- [Fn]-F2.
+ is used to switch between these two modes.
+
+ {\em Note:} On MacBooks and other laptops with compact keyboards, you may need

+ keys. So to toggle between keyboard and normal mode, press [Fn]-[F2].

To select part of an alignment, place the mouse at the top left corner of the region you wish to select. Press and hold the mouse button and drag the mouse to the bottom right corner of the chosen region then release the mouse button.
This selects the entire column of the alignment. Ranges of positions from the
alignment ruler can also be selected by clicking on the first position and then
holding down the [SHIFT] key whilst clicking the other end of the selection.
-Discontinuous regions can be selected by holding down [CTRL] and clicking on positions to add to the column selection. Note that each [CTRL]-Click changes the current selected sequence region to that column, but adds to the column selection. Selected columns are indicated by red highlighting in the ruler bar (Figure \ref{selectcols}).

\section{Reordering an Alignment}
Sequence reordering is simple. Highlight the sequences to be moved then press the up or down arrow keys as appropriate (Figure \ref{reorder}). If you wish to move a sequence up past several other sequences it is often quicker to select the group past which you want to move it and then move the group rather than the individual sequence.
\subsection{Representing a Group with a Single Sequence}
-Instead of hiding a group completely, it is sometimes useful to work with just one representative sequence. The {\sl $<$Sequence ID$>$ $\Rightarrow$ Represent group with $<$Sequence ID$>$ } option from the sequence ID pop-up menu enables this variant of the hidden groups function. The remaining representative sequence can be visualized and manipulated like any other. However, any alignment edits that affect the sequence will also affect the whole sequence group.

\subsubsection{Retrieval of Protein or DNA Cross References}
-The {\sl Calculate $\Rightarrow$ Get Cross References } function is only available when Jalview recognises that there are protein/DNA cross-references present on sequences in the alignment. When selected, it retrieves the cross references from the alignment's dataset (a set of sequence and annotation metadata shared between alignments) or using the sequence database fetcher. This function can be used for EMBL sequences containing coding regions to open the Uniprot protein products in a new alignment window. The new alignment window that is opened to show the protein products will also allow dynamic highlighting of codon positions in the EMBL record for each residue in the protein product(s).
