If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): 2024.2.4
Standard Standalone? (y/n) If not then what?: Standalone

Hello, in older versions of PsychoPy I could access the number of remaining trials in a trials loop named trials with trials.nRemaining. This is no longer possible. Is there another variable which gives me the number of remaining trials (or blocks or whatever is counted down)?

nRemaining worked up to version 2024.1.5 From 2024.2.0 it is no longer working. Any advice would be helpful.

Thanks - Sven

Hello

You are not the only one. There seems to be a bug, see [Bug]: trials.nRemaining not updated while experiment is running · Issue #6852 · psychopy/psychopy · GitHub

.nTotal still works. So YourLoopName.nTotal - YourLoopName.thisN should give you YourLoopName.nRemaining (or whatever you want to call the variable). I would not use n.Remaining. It may work again in future versions.

Best wishes Jens

I’ve never used trials.nRemaining but I suspect that it breaking is an unintended consequence of the new functions which allow you to rewind and skip trials.

Thanks Jens, problem solved.
