Description of the problem:

Hello, i ran some subjects this morning on Prolific. I downloaded the data from Pavlovia. Everything worked great. I added more subjects to the study (no changes to the experiment) and now there are only gz files for the new subjects. Please advise. Thank you.

I believe you will find that you have switched to database from CSV.

I have not. I double checked this; refreshed page (to be sure), etc.

Please check that csv file (trial by trial) is ticked in Experiment settings / Data.

What version of PsychoPy are you using?

I am using v2022.1.1 .  
Yes, ‘csv, trial by trial’ is ticked.

Strangely, all i did was add another 2 subjecst to the experiment, and the newer ones were .gz files.

I re-synced, clicked DATABASE and then back to CSV on the experiment page (Pavlovia), refreshed, double checked the links in Prolific and ran another subject. I will report back, once i get the results. Thanks.

Appears to be working. Thanks.

So, now that I have these gz files, is there a simple way of converting them to the same format as the other csv files? I looked around and information is sparse.

There’s a Python file for extracting data from log files (which the gz files will become if your decompress them using something like WinZip). However, this isn’t something I’m experienced with.

11 more data files had the same issue; this time it was all within the same study, while ~50 other subject data saved as the csv files.
