====== Installation of CLUSTALX 2.0.12 ======

===== Additional libraries =====

The following libraries are required:

   * libqt4-dev

<code bash>
% sudo apt-get -y install libqt4-dev
</code>

===== Procedure =====

Follow this procedure to install CLUSTALX from source code:

  * The archive with the source code has been downloaded from the web site into ''/home/bioubuntu'', decompressed and the created folder moved into ''/opt/bio/sources''.

<code bash>
% sudo mv clustalx-2.0.12 /opt/bio/sources
</code>

  * This folder should belong to ''root'' and its permissions should be set to ''755''.

<code bash>
% sudo chown -R root:root /opt/bio/sources/clustalx-2.0.12
</code>

  * Once you get into ''/opt/bio/sources/clustalx-2.0.12'', compilation is easily performed. You only need to generate the Makefile with Qt first.

<code bash>
% sudo qmake && sudo make
</code>

  * A problem seems to exist every once in a while during the ''make'' process, ''make'' complaining that the moc*cpp files were created with the wrong Qt version. If this occur, you need to do this:

<code>
% sudo rm moc*cpp
% sudo make clean
% sudo qmake && sudo make
</code>

  * ClustalX comes with an installing script which install the executable as well as some auxiliary files at appropriate locations. Use de default value (''/usr/local/bin'') for installing the executable.

<code bash>
% sudo ./installer
</code>

  * You need to add ClustalX2 into the **Impilo > Multiple Sequence Alignements** menu
    * More to come...

  * To use ClustalX2 from the command line:

<code bash>
% clustalx2 &
