All trajectories and plots lost from points in version 1.3.7 and 1.3.8

[Sandra Geiger]

I created an xma-file with several trials (about ten). Two thirds through tracking all trials - after opening the file on a new day - XMALab does not show any trajectories or plots of the marker which were already tracked anymore. The points and their names still show in the Points section, but they're not marked on the X-ray videos nor do I see anything in the Plots window. Restarting and force update trial did not work. I tried in 1.3.7,1.3.8 and 1.3.9 - same result. When converting the file into .zib all the information for the tracked marker is there and when opening the xma- file with XMALab 1.2.17 or 1.2.19 everything is there and working fine.

I encountered the same problem today with a file tracked in 1.3.8 and then opened in 1.3.9

Hi Sandra, Do you have all the avis on your harddisk when you open the xma-file? If so, can you send me 1 dataset for testing? Thanks, Ben

Hi Sandra, The trial K1M_19 is not in the xma-file. Can you upload me somewhere other videos or attach a correct xma file? Thanks. Ben

[Sandra Geiger]

Hi Ben, you are right of course. Sorry, I got confused with too many trials...

Hi Sandra, Did you create the xma-file manually? Or did you just save from XMALab? The version of the xml file inside the .xma is set to 0.1, but the format is actually at least 0.2. This is why it reads some values wrong.However, this should never happen when saved from xmalab. Do you have more information on how it was created?

[Benjamin Knorlein]

I attached a file in which i set the version to 0.2 and it seems to work now. But please let me know if you created the file manually or just saved. In case you created it manually: Please in the future use the File->Import->Trials from xma-file feature to ensure the version is always correct. Ben

Hi Ben, I'm not sure I get what you mean by "create xma-file manually". The files were created in XMALab from tifs, framespec, videos and so on and then saved from XMALab. They were then opened with XMALab with "Open dataset". We did not create a zip-file ourselves and then renamed it .xma, if that is what you meant. I tried your solution on our second corrupted file and it worked. The version was set to 0.1 and when I changed it to 0.2, the file was fine.

[Benjamin Knorlein]

mmh. Ok. this is strange as it should not happen. I assume you imported from files created with a newer version of xmalab into an older version of xmalab. In this way, the trialdata was in the format for 0.2, but you saved it in the older version with format 0.1. Make sure that you always use the newest version of xmalab. I will close the issue.
