Re: hc-5 Position Data

Hello. I'm using this file from the hc-5 data set (i01_maze09_MS.002_BehavElectrDataLFP.mat).

When I plot the Track.xPix and Track.yPix data I get a figure that looks like IMAGE_1 (attached). There are a bunch of straight lines that seem to move back to a central origin, which doesn't seem to exactly describe the movement/position of the animal. What is this and how can I remove it?

Thank you.

Probably that's lost tracking. In this case, you could detect when it's lost (like zeros or -1) and maybe use interpolation.

actually, this animal has two leds? because if you are using the mean between led1 and led2, when one of them is lost, the mean will use zero and the position of the other led. That's another possibility.

Hi. Thank you for responding. This makes sense, but what do I actually need to do in order to view the movement data without the lost tracking? I'm very new to MATLAB. Is there a command I can input?
