Hi, I hope you are well. Could you please assist me. I am trying to pilot my experiment before I take it to run, but whenever I Pilot:Run it on desktop using the current python script while piloting with features on it does pilot in the way I want it to.
However, whenever I pilot it in Browser it doesn’t. In fact, it can show the first image and then it will show the text attached in the picture below. It basically does not pilot at all as it gives me an error.But it doesn’t make sense because I didnt change anything from when I piloted it through desktop and through the browser.
Also, I wanted to ask how many credits do I need to run an experiment 1 time. Like maybe for one participant. Because I bought a few credits but it still says there aren’t enough credits.
Your response and assistance will be greatly appreciated.
Hello @Mataviola
This error message indicates that Pavlovia cannot find the specified file. This is most likely due to a spelling or capitalisation error. Searching the forum for this error will reveal several solutions.

Hi Jens, I hope you are well. The thing is, the experiment is playing on desktop but its not on browser. And I have verified that the items are similar, named in the same way even in the excel that is in the loop.
Have you added the resources in Experiment Settings / Online / Additional Resources ?
Perhaps you have bought credits but haven’t allocated any to this experiment. No credits are needed for piloting.

Hello @Mataviola
Did you try running the experiment locally in a browser, in addition to following wakecarter’s tips? Did you search for spaces in the filenames in your condition file?

Hi, yes, this is the condition file (the excel of the loop). Everything is okay. There are 2 folders that have the target and distractor objects. Each of these folders have the same items that are there in their position (excel), and they are named in that exact way.
Also, this is just confusing because it is piloting in desktop and not in browser, but nothing has been changed whenever I try pilot it in both these places
Also, I forgot to mention. It’s not that it doesn’t pilot in browser at all. It does, but it probably does it for 1 object with its distractor and then it will stop and not continue again. And it’s different bobjects at that
Thank you for the credit feedback, I’ll definetely make use of it when I run the test.
Hello @Mataviola
When you run your experiment offline, it runs in Python. If you run it in a browser, however, your experiment runs in JavaScript. When running offline, the software is able to accept differences in capitalisation. However, this capability is not present when the software is running online. Therefore, offline, ‘murii.png’, ‘Murii.png’ or ‘Murii.PNG’ work, but not online. Please ensure that all file names are written with the same capitalisation as in your condition file. Make the file extensions visible. Sometimes, files are named ‘murii.png.png’ with the second file extension hidden by the operating system.

Hi, I hope you are well.
I changed the names and I have them in the same capitalisation. Nothing has changed. Also, it has stopped playing completely in browser and it only shows the things that are in screenshot, however, there is nothing saved as that in the experiment files (not in the loop excel or in the folder for the distractorr
Thank you so much. Your assistance is really appreciated.
Hello @Mataviola
Do you mind uploading a toy-version your experiment including stimuli and condition file?

Hi, I do have a toy-version of the experiment. But I am not exactly sure how I can upload it here.
Could you assist with that please.
Also, I noticed something. I went to pilot the toy-version of the experiment in browser and it said the error thing that it has been saying for the original version, but the items are not named in the same manner, and not even in the same language.
So, I am not exactly sure if the issue is the browser or if its technical issues in the experiment
