 +==== Installation ====
 +
 +  * Before installing Infomap you would have to install gdbm libraries in your computer. This could be quite challenging. In the following I document the installation process I followed.
 +  - As a first step, you should download the last version of gdbm.
 +  - Untar the .gz file and go into the created directory.
 +  - Try: <file bash>./configure</file>This command should try to configure the program to your system specifications. It is highly likely that this process fails. The most likely reason is that a system library called libtool is not version compatible. To check your version of this program (in ubuntu):<file bash>apt-cache policy libtool</file>. I presuppose you have libtool installed in your computer. You probably have a newer version of libtool as the one presuppose by the gdbm package. The solution I found was to run:<file bash>autoconf -f -oconfigure</file>
 +  - The last overwrote all the libtool-related files in the directory. Now you can run <file bash>make</file> safely. If you obtain the following error -which actually is highly unlikely<file bash>checking build system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized</file>you will need to deceive the program. Add before any command:<file bash>linux32</file>
 +  - You might also have problems with the ANSI c headers. To solve this problem<file bash>sudo apt-get install libc6-dev</file>
 +
 +
 +==== Testing =====
 +
 +The first step in order to build a model is to choose a directory where the models will be created. This is done by setting an environment variable <file bash>INFOMAP_WORKING_DIR=/home/jrandom/infomap_models
 +export INFOMAP_WORKING_DIR</file>
 +
 +Afterwards run build the model. Informap accepts two formats: a single file where documents are divided by xml markers or as set of files, where every file contains exactly one document. I decided to use this second option. As input, there should be a file specifying the name of file containing a document.<file bash>infomap-build -m /usr/local/share/corpora/manyNames.txt many_01</file>
 +
 +Remember to add infomap to your PATH variable.
 +
 +In corpora directory, you will find a simple py script for building a corpora from a file where every line is a document. Afterwards I used the following command:<file bash>infomap-build -m /net/data/CL/projects/wordspace/software_tests/corpora/infoCorpus/directory.txt firstModel</file> 
 +directory.txt is a file contaning the name of every file contaning a document.
