Issues with Uploading a Video to Prepare JAABA Data

[Selam Moges]

Hello!

I've entered "PrepareJAABAData" into MATLAB and reached the pop-up window where I'm supposed to enter the Ctrax files. I've attached the .ann file and .trx mat file. When I'm trying to enter my video file, however, it's not allowing me to click it in my Finder. I've tried .mp4 and .avi formats for my videos, and nothing is working. I'm not sure if there's something I'm not doing that's preventing me from entering videos. 

Would anyone know how to fix this issue?

Thanks so much!
