Empty data results csv files

If this template helps then use it. If not then just delete and start from scratch.

Pavlovia ecp built using
PsychoPy version (e.g. 2024.1.4 Py 3.8):
Standard Standalone Installation? (y)
A colleague has been running an online study however they did’t build in a clean end to the study - it just hangs waiting for ESC or for the tab to be killed. Some work fine but they have some empty results files. Whilst not having a clean end is not ideal, they did have the epxeriment set to save regularly and so I’m surprised they are completely empty.
I’m assuming the data is lost but any thoughts as to whether it might be possible to recover it?
Thanks,
John

Hi John,

Here are my relevant tips:

Wakefield's Daily Tips

Exit cleanly Locally you might want your participant to end on a thank you screen rather than being sent back to the PsychoPy Builder. Unfortunately, this desire has encouraged a bad habit of leaving the final message on screen and then pressing the escape button to exit. While data is saved locally after escape has been pressed, until recently microphone recordings were not. My recommendation would be to have the final screen end on a key press that you have not told the participant, e.g. ‘q’. …

Saving incomplete results When I create a new study on Pavlovia, one of the first things I do is turn off “save incomplete results”. [image] [image] The reason I do this is to avoid having lots of data files getting created while I build and test the experiment. This is especially important if you use credits rather than a licence, since each data file will cost a credit. Even when turned on, saving incomplete results can be a bit hit and miss. The data is always saved if you press escape …

I suspect that save periodically cleans up if you escape and don’t have partial saving on…it’s for crashes.

Are there any log files?
