[EDf export] different result between continious file and imported epoch

Hello,

I just tried to export ~9 hour of data as edf (continious raw file in the database). However, i was keeping having an error at the end of the export (unable to write data to file). This was creating a 1.5Go edf file that could not be open by other software.

I tried to remove the end of the file without success. (extract time)

So then, i tried to import the entire file in the database; and i was then able to export the file as edf without error.

Also, the created file is much smaller (700 Mo).
Do you know what could cause this difference of behavior between continious and epoch data for the export to edf ?

The differences is what in "raw -> EDF" data is read and written in blocks, while in "imported -> EDF" all data is loaded in memory, and the all data is written. I have tried with few "raw" files without troubles.

  • What is the original raw file?
