Extract Trainset Responding Slow about antrax HOT 3 OPEN

Hey Zimai,

By default, the software preloads the images from 50 tracklets when the GUI opens. After that, it will load the images only when you ask for a new tracklet, hence the delay (although 30sec is too much I must say). The cli does not allow you to change this setting, but you can launch the gui from the matlab prompt with:

validate_classifications(<path-to-expdir>, 'N', <num-of-tracklets-to-preload>);

Obviously, the price you pay is a delay in opening the GUI. You can also choose a specific video range to draw tracklets from, or that are classifies with a specific ID (if you are doing a second round training):

validate_classifications(<path-to-expdir>, 'N', <num-of-tracklets-to-preload>, 'movlist', <list-of-video-inices>, 'id', <ID>);

This is not related to your machine, but to inefficiencies in the way anTraX (via MATLAB) stores and access tracklet data.

Let me know if it helps!

Thanks a lot Asaf! However, I think the bigger problem is the point 2 that I listed: the loading process when switching between videos in extract-tracklet takes >10 mins and thus it takes very long for me to build a transet. I am not sure if this can be improved by the machine?

Can you give me some info about your experiment / data? How many videos you have, how many colonies/ants in the frame. how long is each video, whats the order of magnitude of the number of tracklets per video? The delay in loading a file can be a result of a very fragmented dataset (a file containing very large number of short tracklets).
