Ambiguous Dimension Error

[alyssa....@gmail.com]

Hello,

I am trying to track a few dolphin individuals within idTracker, but they are within a pod. Is this possible to do with idTracker because I keep receiving various errors. I have solved all the problems with formatting the videos, but I am stumped by my most recent error message. It reads:

An error has occurred, and idTracker must close. 

The error was

Attempt to grow array along ambiguous dimension.

Error in => idTracker.m at line 946

I am unsure of what to do and if anyone knows if my type of dolphin study would be possible with idTracker please let me know. 

I also want to note that when the tracker follows the individuals it sometimes treats one dolphin as two. (1 as the body, 1 as the tail). These dolphins dive and intermingle between other dolphins within the pod, but there is no way for me to know how many exact individuals there are. Should I type 3 in the number of individuals box when I am tracking only 3? 

Thank you for the help, 

Alyssa
