Dear openvibe,

I had this scenario where the acquisition client was writing in a csv file.
The csv was updated while the acquisition was perform. The scenario was working like that until yesterday.
Today, for some reason, the csv is filled in with the acquire data only when I stop the scenario and not while it is played.
I tried the deprecated csv writer box and this latter is also acquiring and writing at the same time.

What am I doing wrong?

Thank you for your help

Hi, here's some pointers. If you think the issue is in your scenario, please see ... scenarios/

On the other hand, if you think it is a bug, please follow the instructions in

Personally I'm not sure CSV writer box was even consciously designed to be 'streaming'. It might be, just since in OVs streaming architecture, its easy to write data out as it comes, but I'm not aware of use cases relying on such property in the CSV case. In most use cases I'm aware of, the data in CSV is used after the session has already stopped.
