BehaveAI can now measure orientation. So now you can work out the behaviour of your animal in each frame as well as its direction - e.g. tells you which way animals are pointing or whether they're turning. Video guide: youtu.be/FgmtHoardWg Install: github.com/troscianko/B...

Come and work with us (the Kokkonuts) as a postdoc! Our research within (theory-evo-eco) is broad; let's say it's implicitly defined by the journal club papers we read. Which is why the application process includes a JC-related task, I hope it'll be a fun one for you! www.evoldir.net/brian/evoldi...
