 Once this tutorial is completed students will be able to:
 
 - Write the PLUMED input file to perform metadynamics simulations 
-- Calculate free energies from a metadynamics run
-- Assert the choice of the collective variable
-- Evaluate the convergence of metadynamics simulations
-- Compute the error associated to the reconstructed free energies
