Large component split along the wrong axis

[rutvij.k...@gmail.com]

Hello all,

I am wondering if there is any way to modify how Ctrax splits merged components. Mismatch errors are the most common errors that I find in my videos and these occur most frequently due to erroneous splitting of the merged component, typically along the axis perpendicular to the axis of movement. See below figure for reference.

I have tried playing around with several of the shape and motion parameters but haven't been able to find anything that works. I would love to know if anyone else has had similar issues and if they've found workarounds for them.

I found a description of something similar happening in the Supplementary material for Branson et al. 2009 for which the authors proposed to find a fix in the future. Is there such a fix available in the latest version? 

I appreciate any and all help!

Thanks!
