Yes, that's a known issue: https://github.com/smathot/OpenSesame/issues/120 For the Psycho back-end there's currently no real way around this: On some systems the back-end simply ignores the font altogether and falls back to some 'sans serif' defau…

If I understand correctly, your goal is to temporarily use the monospace font (i.e. for the purpose of alignment), but without changing the default font to monospace. Is that correct? If so, the easiest way is probably to define the font style using…

Alignment tags are not supported, unfortunately. The only tags that have been implemented are the ones shown in the example. You can pass the center keyword to a label widget, but this just toggles between left and center alignment, without a possib…

Ah, I see. To use HTML you don't need to do anything special: You can type your HTML tags (just a small subset actually) directly into your sketchpad, form, inline_script, etc. Edit: Only the Xpyriment back-end currently supports all the tags shown…

Hi Jákup, These functions are mostly for internal use, so it's debatable whether they should be included in the documentation. But you could, in principle, use them in an inline_script. Essentially, most of these functions, such as draw_text() ren…

Thanks! → https://github.com/smathot/OpenSesame/commit/5e8c4b3b0cff64c0c5556cc2cce159c23ee59fee

Ok, great! I merged the pull request. Good detective work. I was wondering, though: Why the magic version 1.0.0.28? Do the Eyelink guys say that all later versions do no longer suffer from this bug, and that all earlier versions do? (Maybe I missed…

However when I simply copy pasted yours, the problem does not occur that much. However, there are still changes in the time. Sometimes it jumps between pictures from 100ms to 200ms (or something in between), but these jumps rarely occur! Good! The …

Hi Daniel, However, will only the response and response_time variables be registered this way, or will OpenSesame automatically parse this information further and for instance compare it to the [correct_response] variable to derive the value of [co…

Hi, I'm afraid there's no comprehensive Undo function, except for in the text editor components, where you can use Control + Z as you are probably used to. The reason is that it's quite tricky to implement proper Undo functionality for the GUI-bas…

Regarding the questionnaire plug-ins, the updated version of the plug-in pack should be compatible with OpenSesame 0.27: * http://osdoc.cogsci.nl/plug-ins/questionnaire-plug-ins * https://github.com/smathot/opensesame_questionnaire_plugins/tags I …

Hi Raph, It seems that what you really need is to poll the keyboard and present stimuli at the same time, or at least in rapid alternation. This is quite a common request, but also tricky to do ... hence the new parallel plug-in, which should (once…

"Which back-end are you using? "- I'm using PyGame. We're aware that this unfortunate issue occurs on some systems. For now, you could use a different back-end or the workaround suggested in my previous post. by the way, 0.26 and 0.27 wi…

Hi Michel, Right, I see. Indeed, there is a clear and consistent slowdown. The ITIs for the first trials are exactly 116.66ms, which is what you would expect given a 100ms sleep on a 60Hz monitor (where each cycle is 16.66Hz). If you want to get a…
-
Thank you for your feedback! It would be very helpful if you could provide some additional information. * What distribution of OpenSesame are you using? I.e. the official installer, the Python portable based package? When for some reason you have …
-
You're probably right, I'm not questioning that, but the code I posted potentially gives more insight, because it logs the timestamp for every image. Could you please run that and post the results? Perhaps you could try it with sequences of varying …
-
Hi Michel, You're code looks fine, but I was wondering: How do you check the presentation time? It's probably best to store the timestamps returned by img.show() in a list, and print them out afterwards. It could very well be that presentation is i…
-
Hi Raph, I just began to use OpenSesame, great software ! Thank you! I try to record response time of a short stimulus (15ms) immediately followed by a sketchpad, so the subject can answer after the offset of the stimulus. My problem is that the …
-
Hi Wouter, First off, let me say that this is great work. This is inconsistent with what 'my SR-research guy' says. The start gaze data definitely seems to be incorporated in the event, just set wrong. From the thread I reckon he means that there…

Hi Daniel, Yes, the mouse cursor is a bit troublesome with the legacy back-end. In the back-end settings for the legacy back-end you will see a Custom cursor option. If this is enabled, OpenSesame will try to draw the mouse cursor itself. This is …
-
Hi Caleb, To create an animation, you will have to construct a slideshow of images in which you displace a stimulus with each frame. For example like so: [pastebin:vL2wXzZJ] I'm not sure what the best approach would be in your case, but in genera…

Hi Elizabeth, I would like to make it so the mouse click on the image or circle is recorded according to the circle or image file. I assume the best way to do this for the picutres in the dot condition is with widgets using something like: widget …
-
Hi Michel, I agree that it would be very nice if the loop variable wizard was more flexible (see feature request). What makes it tricky, though, is to decide how to implement this in a user friendly way. The things that you point out are specific t…
-
Ah, thanks for pointing that out. I encountered a similar bug a while back. It should be fixed as of 0.27~pre34. But the issue it's kind of difficult to reproduce, so let me know if it still occurs.
-
So when I log the response variable, in a similar way, it is not a global variable called "response", but a local one, that is replaced by the same variable in subsequent items? Well, the rule is a follows: When a logger self.get()s a var…
-
Thanks for trying to sort this mess out! And, indeed, from what you say it appears that the main problem is that link_event_data has not been properly set. Do you remember whether you have thoroughly tested whether changes in these lines actually h…
-
We've come up with a technique to use frames that are presented as a buffer for the sound which means we can get it to present in a small sequence with an accuracy of 5ms either side of the intended time. So it ranges from 100% accurate to 5ms below…
-
As Boo says (edit: that's not really what he wrote, I see now, but it's still true), you can declare a variable global in order to access it from within other inline_scripts. However, if you want to use a variable as part of a sketchpad, or more gen…
-
Hi Jákup, Just a quick note: Perhaps it's helpful to understand what the count variable actually is, because it's potentially a bit confusing: Every item has a variable that is called count, which simply counts how often the item has been called. …

Thanks (for the manual and the work on the Eyelink plug-in)! Daniel submitted the changes, and I just pushed out an update: https://github.com/smathot/opensesame_eyelink_plugins/tags
