Hi, I am trying to pilot an experiment on Pavlovia. For many-many days, the incomplete csv data was saved locally, so I could check things (e.g. which trial generated the error etc). This stopped yesterday, despite the Save incomplete data is ON. I have the problem both when using @wakecarter ’s web …

[image] danna: Another issue is that the exp stops running when it gets to a certain image, saying unknown resource This isn’t another issue. Your experiment is crashing, which is why it isn’t saving data. Is it always the same image? There might be a space in the filename, or the file could…

Hi, Interesting. So far I had data saved locally whenever errors popped up…I found the root cause (one of the many conditions files, one parameter of the image was somehow missing)

Locally data saves incrementally, so you get data on a crash. Online it saves at close, so a crash can’t save anything (unless you have periodic saving turned on, which I haven’t explored)

I had data when piloting online. The periodic setting was turned on. Anyways, I found the cause, so hopefully it will be okay. I know this is an unrelated problem but I don’t wan’t to start another thread: Did anyone find any solution for the blurriness of the images and texts?

Here is the thread about what we currently know about online blurriness. Feel free to add a new post there. [image] Blurry / low resolution online Online experiments Hi all, For some reason, my online experiment is running at a much lower resolution than it i…

Hi @wakecarter , No datafile (csv) is saved in piloting mode, even if I complete the whole test (no crashing). I get the survey results (they are automatically downloaded) but nothing else, though previously this worked. Save incomplete results and Save periodically are on. I would really need to loo…

I would turn off periodic saving and try again. Do you have any code in End Experiment?

Hi, There is another short pavlovia survey (a debriefing one). And, maybe that is the issue! Previously I had a ‘thanks and goodbye’ routine at the end and nothing else. I will try to re-add this routine after the survey and run the experiment again this way (with and without periodic saving turned …

Hi @wakecarter , So It does not save data in pilot mode, whatever I try. The experiment is “completed”. It is listed as “submitted” but only the survey is saved locally at the end (json file). This happens both when the Save periodically option is on and when it is off. Save incomplete data is on (it…

Try adding a short routine (1 second blank screen or “Please wait” should be plenty) in between the end of the last embedded survey and the end of the experiment.
