Two problems with Tracker 6.0.10

First problem: Setting the length of the calibration stick, after the tracking of a mass  point has been completed, the data table is not automatically updated. I have to press play button for the video to be reproduced and then the data table is updated. The same happens when I change the orientation of the axes from the toolbar.

Second problem: Defining a new fit function in data tool is not working. See attached picture.

I don't know if these are known problems:

When i enter very small numbers (e.g. 0.02 m) in the text field of a calibration bar, Tracker ( v. > 6 ) does not accept them, failing in the attempt to convert them into scientific format ( x.xxxe-y ). As a result the experimental data (position coordinates) that i get after tracking, are incorrect. The same happens entering the mass of a point mass.

I can't reproduce this problem on my Windows 11 machine. Can you give more details? Please use the troubleshooting guide at https://www.compadre.org/osp/items/detail.cfm?ID=16061  Doug

My system is Windows 11 (Greek). Many friends here in Greece have the same problem. Attached image shows what exactly the problem is.

Hmm, that's a mystery. I notice you are using a period for the decimal separator. Isn't comma the default for greek? Did you set the decimal separator to a period? What happens when you use a comma?

Hello,

yes this could be a regional settings issue.

you can try the comma from windows regional settings and see if tha resolves the issue.


greek user here too, but haven't used tracker for a while.

I've already tried that, but to no avail.
I actually assumed that changing from the default decimal point (comma) to period would solve the problem, but as i said that doesn't help.
Tracker 5.1.5 works fine. Maybe is the 64bit Java engine that causes the problem...

Finally problem solved installing Java JRE 8 (jre-8u351-windows-x64.exe).

Defining a new fit function in data tool (as i mention in my first post) still is not working.

Defining a fit function will be fixed in the next release. Probably within a week or two.

What JRE version were you using that caused the bug?  Why aren't you using the bundled JRE?

The problem occurs with the bundled JRE (v.9.0.4). As i said problem solved using JRE 8. But it is very strange that with JRE 8 the model builder window does not open, unless the GUI font size is set to the smallest one!!!
