 outputs its persistence diagram.
 
+The file should contain square or lower triangular distance matrix with semicolons as separators.
+The code do not check if it is dealing with a distance matrix. It is the user responsibility to provide a valid input.

+Note that no check is performed if the matrix given as the input is a correlation matrix.
+It is the user responsibility to ensure that this is the case. The input is to be given either as a square or a lower
