All cameras stopped collecting data without Miniscope DAQ software error

[Jessica Froula]

I had an issue yesterday when I recorded from a mouse (v4 miniscope + 2 webcams, Miniscope-DAQ-QT software) and after the recording was finished (~1hour), I noticed that something had happened along the way where empty video files started being produced. Of note, I had recorded from other animals that day without any issue. After the first few videos all the other videos produced contained 0 bytes of data. E.g., for the miniscope, the first 5 videos contained data but the remaining ~60+ videos had no content . This was also reflected in the timestamps--the first ~5k frames of the scope were recorded and then, from the timestamp file, it looked like the recording had ended. 

Despite this issue I discovered after the fact, I didn't notice any errors or disconnections of the scope on the control panel. As far as I can tell, everything was running normally. Has anyone else encountered this issue?

Thanks in advance for any help!

Did you have enough free space in your hard drive for the whole recording?

This was definitely the issue after many recordings over the last week and not removing the older ones from the drive. I'll be keeping better track of that moving forward. Thank you Federico!
