<div dir="ltr"><div>Hi Cassandra,</div><div><br></div><div>I agree with the answer by Damian Lidgard. As I understand it, you define a "visit" period (in order to see whether 2 points in the same area is part of a single visit or a revisit). Typically, for predators I used the longest period they would stay on a single carcass. So if your sample frequency is longer apart than the "visit period", there is no way to classify it as anything else than a revisit. I would analyse the 2 periods separately.</div><div><br></div>HTH.<div>Chavoux Luyt</div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Op Do. 26 Nov. 2020 om 07:10 het Cassandra Arkinstall <<a href="mailto:cassandra.arkinstall@gmail.com" target="_blank">cassandra.arkinstall@gmail.com</a>> geskryf:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif"><span style="font-size:11pt">Hi all, </span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif"><span style="font-size:11pt"><br></span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif"><span style="font-size:11pt">I am new to tLoCoH and have a question about the sampling frequency graphs.
