The first integer is the number of samples n. Following, we have n triples that
describe the animal ID, specie (D: deer, E: elk, C: cattle), and number of
observations (number of points in the trajectory for that animal).  The specie
and number of observations information is not used for any specific propose.
After that, we have an upper triangular matrix describing the similarities.
Each index of this matrix corresponds to a animal in the order that they are
described before.

ID1 specie # of observations
ID2 specie # of observations
