The following libraries are required:

• libqt4-dev

% sudo apt-get -y install libqt4-dev

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.

% sudo mv clustalx-2.0.12 /opt/bio/sources

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

% sudo chown -R root:root /opt/bio/sources/clustalx-2.0.12

• 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.

% sudo qmake && sudo make

• 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:

% sudo rm moc*cpp
% sudo make clean
% sudo qmake && sudo make

• 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.

% sudo ./installer

• You need to add ClustalX2 into the Impilo > Multiple Sequence Alignements menu
  • More to come…

• To use ClustalX2 from the command line:

% clustalx2 &
