revert the update) until a fix is listed on the status of the gamma bugĪltering your monitor settings in Windows (e.g. Team can do until Microsoft fixes the underlying bug. If you do need gamma correction then there isn’t much that the PsychoPy ® (rather than ‘abort’) and then your experiment will still at least run, To the preferences and set the defaultGammaFailPolicy to be be ‘warn’

If you don’t need gamma correction then, as of PsychoPy ® 3.2.4, you can go This only occurs in certain scenarios, like when the screen orientation is in portrait, or when it is extended onto a second monitor, but it does affect all versions of PsychoPy.įor the Windows bug the workarounds are as follows: In Windows release 1903 Microsoft added a bug that prevents getting/setting the gamma ramp. Paste the following into that window (Ctrl-V doesn’t work in Cmd.exe but you can right-click and select Paste):

Windows users (starting from the Command Prompt):ĭid you get an error message that “This application failed to start because the application configuration is incorrect. I also have code for a few typed responses but since I took (and modified it a little) the code from the Pavlovia Demo Experiment textinput and there’s no random in it, I guess this is not causing the issue. The way to get that message depends on the platform (see below). If resetting the preferences files doesn’t help then we need to get to an error message in order to work out why the application isn’t starting. To fix that see Cleaning preferences and app data, below. Before the experiment I define in a code routine in the Begin experiment tab the following. What this means is that an error has occurred during startup itself.Ĭommonly, the problem is that a preferences file is somehow corrupt. The issue I am having lies in a variable not being recognized. If you do not enter the approximate duration it will not be drawn, but this will not affect experimental performance.You may find that you try to launch the PsychoPy ® application, the splash screen appears and then goes away and nothing more happens. This simply allows components with variable durations to be drawn in the Routine window. because it is a variable) you can enter an ‘Expected’ start/duration. In cases where PsychoPy ® cannot determine the start/endpoint of your Component (e.g. in the authors own lab Python is used not only for stimulus presentation but.

Duration can also be varied using a code component. PsychoPy is a software library written in Python, using OpenGL to generate.

The duration of a frame (in seconds) is simply 1/refresh rate in Hz.Ĭondition would be used to make Components start or stop depending on the status of something else, for example when a movie has finished.

For example if the screen has a refresh rate of 60Hz you cannot present your stimulus for 120ms the frame rate would limit you to 116.7ms (7 frames) or 133.3ms (8 frames). Measuring duration in seconds (or milliseconds) is not very precise because it doesn’t take into account the fact that your monitor has a fixed frame rate. If you need very precise timing (particularly for very brief stimuli for instance) then it is best to control your onset/duration by specifying the number of frames the stimulus will be presented for. For example if you used np.average ( 1, 2, 3) in a code component, you would get the error message np is not defined (to avoid this specific error use average ( 1, 2, 3) - dropping the reference to numpy). Duration can also be varied using a Code Component. You may have used a python library of PsychoPy object that does not exist, and is therefore not defined, in JavaScript.

Condition would be used to make Components start or stop depending on the status of something else, for example when a sound has finished. Am getting below error after running code using python2.7.18. Start and stop times can be entered in terms of seconds ( time (s)), by frame number ( frameN) or in relation to another stimulus ( condition). In the nReps box of that loop, I have used int (conditional) and then in the routines before the loop I have custom code that tells the program when the conditional variable is True or False.

Defining the onset/duration of components ¶Īs of version 1.70.00, the onset and offset times of stimuli can be defined in several ways. In my experiment I have a loop that is only some of the time, other times it is skipped.
