A short recall on howto install/compile a program

1. Get the barriers source from http://www.tbi.univie.ac.at/RNA/Barriers/
2. extract the archive and go to the directory

   			  $ tar -xzf Barriers-1.5.2.tar.gz
   			  $ cd Barriers-1.5.2
   

3. use the -prefix option to install in your Progs directory

   			  $ ./configure --prefix=$HOME/Tutorial/Progs/barriers-1.5.2
   

4. make install

   			  $ make install
   

Now barriers is ready to use. Apply the same steps to install treekin. Note: Copy the barriers and treekin binaries to your bin folder or add the path to your PATH variable.
