This problem on slurm systems has persisted since I developed anTraX, and I couldn’t find a good explanation for it. As Zimai noticed it usually disappears upon a rerun, and is probably related to highly fragmented graphs. My best guess is that something in matlab doesn’t work properly on these highly parallel systems, and that it relates to the .mat file format.
i had a plan to completely change the way anTraX stores it’s data, in hope it will solve the issue or at least will not require rerunning everything. Unfortunately I can’t say when I will have time to do this, or if it will actually help.
Sorry I can’t h lol further at this point :-(

Do the first two files have the variables that were not found ('G' and 'trjs' accordingly)? How does the solve 1 log file look for all three? Anything abnormal compared to the "good" videos? Any errors in the track logs?

Did you try opening these files with MATLAB on your local machine? Is the file size of the corrupt files seems reasonable (e.g., compared to "good" .mat files?
Are you running the latest antrax version on all machines?

Yes, I tried to open these files on my local machines, I can open the file graph of when the error was "Variable 'G' not found" and "Variable 'trjs' not found". But for the "File might be corrupt." it is indeed corrupt. I am running the latest version from the 'master' branch on all machines.

Thank you, Asaf, for the insight! Following this, Do you think it will help if I can concatenate my videos into longer ones to reduce parallels, and see if that improves the outcome? Have you tried to do something like this before?
