Hi Amihai, There are multiple ways to do this, either with a script or coroutines item, but the easiest way depends on what you want to do exactly, and what you have programmed already. Could you upload the experiment here? Cheers! Sebastiaan

Hi Amanda, You'll want to take a look at this discussion. Cheers! Sebastiaan

Hi Sam, If you look under Menu → Tools → Example experiments, you will see that there's a Stop Signal Task for your inspiration :wink: Cheers, Sebastiaan

Hi, The easiest way to do that is to simply add a column to the loop table that contains an identifying value. If you look at the Extended Template, you can see that practice_loop and experimental_loop use the variable practice in exactly this way.…

Hi Hanna, That's very odd. Could you upload the experiment here so that I can see if I can reproduce it? Cheers! Sebastiaan

Hi, This is a known issue in OpenSesame 3.2, resulting from the new way in which text is rendered (otherwise a big improvement). For now, you can use a workaround described here: * https://forum.cogsci.nl/discussion/4155/ Cheers! Sebastiaan

@Edwin Do you know exactly what you can expect with the SMI calibration? You implemented it yourself, right?
-
Hi, In the loop item, if you set the order of the table to random and the repeat value to less than 1, you will randomly sample a proportion of the rows in the table. For example, if you have 100 rows and set repeat to 0.5 with a random order, you …

Hi, It's a bug in OpenSesame, which was indeed introduced when forms were reworked in 3.2. For now, you can workaround it by setting the timeout to 0 milliseconds. So instead of set only_render yes, you would use set timeout 0. For all practical pu…

Hi, This strikes me as an incompatibility between mousetrap_form and OpenSesame 3.2, in which the form functionality has been reworked. So if you want to use that plugin, I would stick to OpenSesame 3.1 for now. (Ping @Pascal) Cheers! Sebastiaan
-
Hi, This error occurs when the main script of OpenSesame is missing. But how this can happen is unclear to me. If you go the OpenSesame folder (i.e. the folder containing opensesame.exe), is there a subfolder called Script, and does it contains a f…

Ah, I see. This is a known issue caused by the External Runner. You should be able to fix this by selecting the Multiprocess Runner under Menu → Tools → Preferences.
-
Hi, I don't know what could have caused this, but let's find out: * Before running the experiment, make the debug window visible (Ctrl+D) * Run the experiment. This will probably crash as it does now, leaving the user interface deactivated. * In t…

Hi, This sounds very much like this Mac OS-specific issue, which has been fixed a while back in 3.1.7. Could that be it? Are you running an older version of OpenSesame? Cheers! Sebastiaan
-
Hi Russel, The fixation_dot item is very old, and not included by default in recent versions of OpenSesame. Why not simply use a sketchpad and draw a fixation dot on it? Regarding your specific question: If the fixation_dot is listed in the plug-i…

Good to hear you figured it out!
-
@Daniel Thanks! The updated package is online now.
-
Hi Russel, Thanks for bringing this to our attention. That's definitely a bug in the Mac OS packaging. I'll roll the Mac OS link back to 3.2.4 until it's fixed (which should be soon). Cheers, Sebastiaan
-
Hi Ali, That's pretty awful, thanks for pointing this out. It seems to be a bug in the GUI toolkit that OpenSesame uses (PyQt5), so really solving it won't happen until this has been cleared up in the toolkit. However, as a workaround you could def…

Hi Emilie, Is that computer online? Because you need an internet connection to download the packages. If it is, then you can also upgrade scipy and numpy by running the following commands in the debug window: import pippip.main(['install', 'scipy…
-
Hmm, this seems to be a compatibility issue with scipy, a common library with scientific algorithms. The synth uses this to generate sounds. The best I can think of is updating scipy and numpy. You can do this by opening the Menu → Tools → Python p…
-
Ah, I see. Columns D, E, and F don't contain any real values, but they do count as empty columns because they have formatting. And therefore OpenSesame complains that they don't have a column name. Do you see what I mean? Clearing the formatting of…
-
(Quote) Ideally, yes! But this behavior comes from pygame, which uses different video modes for full-screen and window modes. So it's not something that can easily be fixed by OpenSesame.
-
Hi Emilie, And what happens in you run from scipy import signal in the debug window? Again, could you post the full error message (if any) here? Cheers! Sebastiaan
-
Yes, I filed a bug report here!
-
Hi Gérard, An Excel file can have multiple sheets, and OpenSesame tries to read the one that is active, which is not necessarily the first one. Could that be the issue? If you switch to the sheet that you want to use, and then save the Excel file a…
-
Hi Russel, (Quote) Yes, you need to open it up. A PCI card is something that goes inside the computer. But do you really need a parallel port? They are awfully old-fashioned and hard to use. If it's just for eye tracking, then you probably need it…
-
Hi Bruno, It took me a while to figure this out, but it's fixed in the latest prerelease of 3.2.5 (now 3.2.5.a6). You can update through pip or, if you're running Ubuntu, through ppa:smathot/opensesame-kuhn. Alternatively, you can simply insert th…

Hi Roelof, What happens if you select one of the themes under "Basic and High Contrast Themes"? Those will not use any of the fancy aero graphics, which may interfere with V Sync. Cheers! Sebastiaan

Hi Martina, This appears to be a character encoding bug in PyGaze. If you select a logfile location that doesn't have any special (non-ascii) characters in it, does the error go away? Cheers! Sebastiaan
