Body: <p>I've been using PAMGuard's click detector + TMA module on a towed array dataset (four-channel soundtrap) to get localisations of finless porpoises. I get very strange results when I use the new version (2.02.03) vs the old one (1.15.17) (Images attached of the same sound file folder). I am using the exact same hydrophone array file and the same click detector settings. The user groups are also the same (hydrophone 1-2 as group 0 and 2-3 as group 1). Ive tried keeping the echo detector on and discarding echoes but nothing seems to fix the problem. I'm sure I'm missing something but I can't figure out what. Any suggestions would be really helpful!
