Hi Tom, Thanks, and welcome to the forum! Whether PyGaze is multithreading-safe depends on what OS you use, and what you're doing in each of the threads. Under Linux, trying to communicate with the X server from different threads results in a hard…

Thanks, guys, for all of the suggestions and notifications about bugs and link rot. The (long overdue...) new version is now online! download OpenSesame 2.8.3 Portable

Hi Ben, Very good question! What you could always do, is generate such a character outside of OpenSesame (e.g. using GIMP), and display the image using a sketchpad. Obviously, it would be nice to generate any kind of character online too. What kin…

Hi Merle, Ramping the brightness of the screen will not be difficult. You could use the script below in an inline_script item. Simultaneously ramping the sound will be tricky, though, as sounds presentation on most computers is subject to unpredict…

I have never used Data Viewer, so I'm afraid I do not know the answer to this one. Maybe you can ask about this on the SR Research support forum? You will need to create an account first, which requires some details, but other than that it's free. …

Welcome to the forum! OpenSesame supports random randomization and ordered presentation. For all other kinds of ordering trials (pseudo-random constructions or Latin square), it is advised to create a trial order outside of OpenSesame and to copy t…

Welcome to the forum! Good job on sorting things out, and thanks for sharing the solution on the forum! Will mark this as solved. EDIT: just noticed that you already did so, cheers!

Hi Hansika, Congrats on the publication! :) I'm sure @sebastiaan will update the publication list as soon as he has time. There are plug-ins for EEG studies. That is: plug-ins to send triggers to your EEG recording device, so that you can parse th…

Welcome to the forum! The documentation for form buttons can be found here. Regrettably, it's not possible to change the colour. Your solution would be a very good one, though! Also, if the reason you want your button coloured is to show it is acti…

Hi Marie, Very good to see you figured things out using the forum; I'll mark this one solved. Good luck with your experiment! Edwin

How dare you suggest I'd be a Windows 8 user!? ;) What you might want to try, is to keep OpenSesame busy during the ITI, e.g. using an inline_script like the following: # get start timestampt0 = self.time()# create a mouse objectfrom openexp.mouse…

Hi Olya, Replace exp.eyelink with exp.pygaze_eyetracker, and everything should work the same. Good luck!

Hi guys, You're correct! The data file character maximum for an EDF is 8 characters. Omitting the "subject-" prefix is the easiest way to solve this, but I agree that it is a bit annoying to have to do so manually. We could simply omit i…

Hi K, You could define the video files and the corresponding sound file within a loop item, e.g. in four variables: vid1, vid2, vid3, and snd. The sequence that is associated with this loop, could look like this: # NOTE: this is NOT code, this is…

Hi, and welcome to the forum! When you say "normal pc", I take it you mean Windows? What version of OpenSesame are you using? Standalone (i.e. installed using the installer), 2.8.3? 1) This depends on what you expect. The code you use te…
-
Hi Olya! Does this mean you fixed this issue? Some troubleshooting: 1) Have you set the correct display size? This might result in the targets being drawn off-screen in some back-ends. Example: if your screen is 1024x768 pixels, you shouldn't set…

Hi K, In general, an overview of the available plug-ins (and information on them) can be found here. How to install a plug-in is explained here. What you will want to do, is to download one of the video plug-ins. There are a few of those, some of …

No worries! Don't hesitate to post any further questions you might have about the source installation (or anything else that pops up).

Hi guys, In the graphical environment, you can use the pygaze_log plug-in to log a message to the EDF file. The exact same is achieved using exp.pygaze_eyetracker.log within an inline_script. For both, you needn't import anything at the start of y…
-
The PyGaze plug-ins work in the same way, but the instance for tracker communications is named slightly different: exp.pygaze_eyetracker.log("this ends up in the EDF") BTW: The PyGaze plug-ins are still in a testing stage. You are advise…

You're using the standalone version, which comes with its own Python environment. This acts completely separate from your Python installation. To be able to use pylink, you will need to run OpenSesame from source. For more information, please see t…
-
Hi Olya, The experiment order seems correct, so that shouldn't be a problem. Are you running OpenSesame from source? Or are you using the standalone version? If the latter is the case, please look at these instructions to configure OpenSesame to al…

Hi! Asuming you are in Windows, log in as an administrator and try again. Your account apparently does not have the rights to make changes to some files (presumably in the Program Files). BTW: Please keep in mind that you will need to run OpenSesa…

Closed as a duplicate of this thread.

The ID integers are for the AOIs, not for the different photos. The absolute coordinates can be calculated: simply add half of the screen size to the relative coordinates (that use (0,0) for the centre). Example: Coordinate (0,0) is the screen cen…
-
Hi Masoud, I think the fastest way of achieving the behaviour that you wish to see, is by using images of the words rather than actual text. To my knowledge, there is no way of connecting the individual characters. That being said, @sebastiaan is o…

Hi, The short answer could be a bit frustrating, but is very clear: You should not be having any repeats in the picList after shuffling it. There could be repeats, however, if there is more processing being done on the list later on! Another possi…

Hi Olya, How is the experiment set up? Are you using the EyeLink plug-ins, or an inline_script to do the tracking? Also: is the eyelink_calibrate the first of your EyeLink plug-ins, and is it located at the start of your experiment (that is: within…

Have you tried pressing 'q' a second time? The blank screen you are seeing might well be the menu, which is not drawn due to some underlying error. To confirm this theory, either press 'q' a second time, or press 'Enter' after pressing 'q' the first…
