Prediction with track identity

[Levans5]

I am new to using SLEAP and currently working on a multi-animal project where I need 3 tracks. When I ran Inference on a 1000 frame clip for practice there are long instances of lost identity where a new track is generated for 50+ frames. Is it possible to select an animals inference in all 50 frames at once and switch its track to be the correct one? Thanks.

Hi @Levans5,

It is possible to switch the entire selected track via proofreading (from the current frame to all subsequent frames - no previous frames will be switched):

1. Ensure "View" > "Color Predicted Instances" is on

2. Ensure "Tracks" > "Propagate Track Labels" is on

3. Go to the frame where the track switch initially occurs

4. Click on the instance you would like to switch the track of
   
   Fig 1: Instance selected.

5. Hold Ctrl to see numeric track labels pop up (in upper left of GUI)
   
   Fig 2: Numeric track labels are listed in the parentheses.

6. While holding control, select the track number to switch to, i.e. Ctrl + 1

Let us know if that is what you were looking for.

Thanks,

Hi Liezl

Thank you. I understand that this can be done one frame at a time. However, say an animal is assigned track-3 for 30 frames in a row is it possible to select those 30 frames for that instance and change the animal to be track-2 (the correct one). Or do I have to go through every single frame individually to proofread and make corrections.

Hi @Levans5,

Selecting "Tracks" > "Propagate Track Labels" should propagate the new track label for the 30 frames in a row - you do NOT need to go through every single frame individually.

Thanks,
