[solved] ISI

mfp49mfp49
edited December 2020 in OSWeb

Hi there

I am using the inline script with the following details:

import random

ISI_options = [1000,1500,2000,2500]

ISI = random.choice(ISI_options)

exp.set('ISI', ISI)


When I use OSWEB, it shows an error as follows:

Uncaught TypeError: Cannot read property 'apply' of undefined


Please could you kindly advice what to do helps replacing the relevant commands to have it run on the OSWeb?


Peace,

Masoud

    Hi @mfp49 ,


    Herewith the JavaScript translation. Make sure to put this code in an inline_javascript item rather than the classical Python inline_script item.


    // Define the array with the possible ISI durations:
var ISIArray = [1000, 1500, 2000, 2500]
// Get a random number between 0 and the length of the array:
var randomNumber = Math.floor(Math.random()*ISIArray.length)
// Use this number as the index to determine the selected ISI
var ISI = ISIArray[randomNumber]
// Store the ISI in the vars object
vars.ISI = ISI


    I attached a simple example experiment.


    Cheers,


    Lotje
