====== Installation of CLUSTALW 2.0.12 ======

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

None required

===== Procedure =====

Here is the procedure to install CLUSTALW from its source code:

  * The source code archive was downloaded and put under ''/home/bioubuntu'', decompressed and the created folder is moved toward ''/opt/bio/sources''.

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

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

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

  * Once you are in ''/opt/bio/sources/clustalw-2.0.12'', compilation is easily done:

<code bash>
% sudo ./configure && sudo make
</code>

  * Because EMBOSS is looking for clustalw, not clustalw2, we need to change the name. We also need to make it available to all users:

<code bash>
% sudo ln -s /opt/bio/sources/clustalw-2.0.11/src/clustalw2 /usr/local/bin/clustalw
