what I understood, the actthrvalue parameter should depend on my highpass filter ("if you highpass filter your data at 10 Hz</span> and have a sampling rate of 1200Hz, you shouldn't find any <span>autocorrelation above 120 samples" --> seen in other thread
). In my case, since I highpass at 0.1Hz, I shouldn't find any autocorrelation above 10240 samples, but since I don't even have that amount of samples and the act is lower than that anyway, this

Also, in my case, it is common that the tau and dimension that I get, are always the lower values that I give in the options. <span style="font-family: Calibri, Helvetica, sans-serif; background-color: rgb(255, 255, 255); display: inline !important">For example,<span> with</span></span><br>
