Problem [Visualizer]: Video playing is slow or choppy
Solution: If the video being visualized is large or highly compressed, reading the video frames can be time consuming. One of the following tips might be helpful:

• Save video in grayscale (1 color channel rather than 3) since the tracker converts all images to grayscale before processing.
• Save video with low compression before tracking and annotating it. (Compress at a later time for space saving reasons.)
• Use only as much spatial resolution as you need for your task.
• If you have recorded multiple chambers, you could crop the video along chambers and store it as multiple smaller video files.
• If none of the above seems feasible, you can visualize the video with "show image" disabled. This way you can scan through the video fast, looking only at the tracking overlay, and once something interesting comes along enable "show image".

Question [JAABA support]: How do I run JAABA on FlyTracker data?
Answer: Download featureConfigEyrun.xml and save it as JAABA/perframe/params/featureConfigEyrun.xml (which might replace an earlier version of the file). When you start a new JAABA project select eyrun_flies as target type. If you have multiple flies tracked in an arena, relational features are not computed by FlyTracker, in that case click [advanced] --> [choose perframe features] and select only features log_vel to dist_to_wall_diff2.

Problem [JAABA support]: Cannot write softlinks on Windows (copying movie instead)
Solution: This seems to be a common issue for Windows 7 and 10 (possibly other versions that we haven't tested). If you are receiving a message that says "you do not have sufficient privilege to perform this operation", the reason is that the current user does not have permission to write softlinks. To change that, take the following steps (source):

0. For some odd reason, "Administrator" users cannot write softlinks, even with the necessary permissions. Before you start, make sure that the user that is used to run Matlab is a "Standard user" and that you have access to another account that is an "Administrator" user.
1. While logged in as an "Administrator" user, launch secpol.msc via Start or Start --> Run.
2. Open Security Settings --> Local Policies --> User Rights Assignment.
3. In the list, find the "Create symbolic links" item, which represents SeCreateSymbolicLinkPrivilege.
4. Double-click on the item and add your "Standard user" to the list.
5. You may need to log out and in for the changes to take effect.
