Description of the problem: Hi All, I have the following code in my python script using builder. with open(‘coordinates.csv’) as file: coords = [line.split() for line in file] Can anyone point me to where I can translate this into JS? The variable coordinates should essentially be a list of list…

@TheSav , you will also need to import the conditions file via experiment settings - online tab using “additional resources”, so that the PsychoPy compiler picks up the file and sends it to Pavlovia. Not sure about that error, but try opening the “null” and “FATAL” tabs, and hopefully there will be…

I’ve also tried manually adding the array to Psychopy to dodge the file open issue (the list has ~2000 items) but if I do this then I get the following error when trying to sync to Pavlovia (the error goes away if I shorten the list to few items). Traceback (most recent call last): File “C:\Progra…

Hello TheSav, Windows has a file path limit of 260 characters. You might want to shorten your path. In Builder usually everything is in the root directory of the experiment (some prefer specific directories, e.g. stimuli, audio aso.in that root directory), so the path shouldn’t be too long. Any rea…

HI Jens. The issue is that I have created a motion path that allows a circle to smoothly move around the screen in a seemingly random fashion using bezier functions. At present this generates about 2000 pairs of coordinates. My program works perfectly fine locally but of course as soon as I attempt…

PS. The coordinate pair are changed every frame update which I why I don’t just import the file as a condition file. The array gets used in the single trial which has ~2000 frame updates.

@TheSav , take a look at this post - you can use a trialHandler to handle the file import [image] Read from xlsx in javascript Online experiments @pinar , you will not be able to import Python libraries in the JS code, so you will need a different solution. The easiest opt…

Thanks David. I’ve applied the code and now it’s pushing online. But I’ve hit a JS code error. Unfortunately my debugging skills at this stage are poor so I don’t know how to interrogate the code at this point. The closest I get is shown in the image below. What’s the easiest way to pinpoint the of…

Thank you David, I managed to use that code to get it to work. The javascript error appears to be specific to my machine and more specifically only chrome. It runs on others’ machine in chrome but only on firefox on mine.
