Markov process: initial values ​​in EstimatedProcess with Gaussian HiddenMarkovProcess

I am using the following code to obtain states and transitions of some traces:

class = HiddenMarkovProcess[2, "Gaussian"];
hmm = Estimated process[traces, class];

However, for some traces (1,4 and 8), the function Estimated budget it does not find the correct states:

How can I set the initial values ​​to the Estimated budget function?

According to the documentation, it should work as Estimated process[data,proc,{{p,p0},{q,q0},…}], but I do not know what to enter for p, q, etc.
