Hi. I am not sure why the computed vectors were not saved (24+ hrs. worth of processing gone). Please help. Thank you.

I am also not sure why.

Haha...maybe if the data is too big it doesn't save the complete session with the vectors? In my case, the image pairs reach around 45k. Or if there's a condition that it only saves the computed vectors once they've been filtered out already?

Hi, but I can't help as there are no details. No error message in MATLAB? Did it finish saving? How large is the mat file?
MATLAB has some restrictions on maximal variable size in a mat file. It also has restrictions on RAM usage. If you want to debug this error,then you need to consider these points.

I tried to re-run it using the newer version 2.38. It saved the vectors. But it v. 2.31, it still didn't save after the re-run. Thanks

Yes, this is a known bug that was fixed half a year ago. Please always use the latest version.
