      <DESC>boolean variable: false - simple least squares, true - constrained least squares. For details see the VOTCA paper. Practically, both algorithms give the same results, but simple least squares is faster. If you are a mathematician and you think that a spline can only then be called a spline if it has continuous first and second derivatives, use constrained least squares.</DESC>

Atomistic trajectory, specified with --trj option, is divided into blocks and the force matching equations are solved separately for each block.
