Answers.Text: Thank you for your answer! I'm pretty okay doing it as a manual analysis, but I wanted to have something more automated. And in theory the PAMGuard function works for that, but I didn't understand how

Body: <p>I tried to find online resources on how the click train function of the click detector (the in-built click train detector), in PAMGuard, works. Unfortunately, I didn't find anything useful.

  Does anyone know of some material I can learn by?</p>

Comments.Text: Hi Jamie. I tried the in-built function with sperm whale's recordings of echolocation clicks. It was for "fun", because not part of my project. I wanted to learn how to use it for future studies. I am not sure what kind of screenshot I can publish - one with the bearing time display?

  I cannot talk about PAMGuard, maybe Doug will chime in.
  
  Typically, I would consider a click belonging to a click train, if
  
  * the Inter-Click-Interval (ICI) does not change very much,
  * the pulse power estimate is peaking up and is either similar to previous clicks or is part of a scan
  * in case you see the intra-head reflection (IPI), then this IPI should be constant (apert from measurement errors)
  * you can identify a surface reflection trailing the direct arriving click and this delay should also vary not much, but may have a significant trend
  
  This is rather easily done with Excel with a single sperm whale, but become a little bit more complex if you have multiple sperm whales
