• Hi Neon, There was indeed a version (3.1.7) that sorted the columns of the loop table alphabetically. That was a bug due to a change in DataMatrix but was solved as of 3.1.8. So upgrading should solve the issue. Cheers! Sebastiaan

  in Has the column order in DataMatrix object changed in semi-recent versions of Opensesame? Comment by sebastiaan January 2018
• Thanks for pointing this out again. What if you try 3.2.0a26 or later? It should be completely fixed now.

• @AgnèsG Do you have an accent in your username? If so, then this could also be a character-encoding issue. Because I see a missing 'e' in the 'agnes': Couldn't open c:\users\agns\appdata\local\temp\expyriment_tmp\tmp5mtxf0.tga

  in Extension OpenScienceFramework misbehaved on event open_experiment (see debug window for stack trace Comment by sebastiaan January 2018
• Hi Patricia, Thanks for your feedback! Have you tested all of the above with the latest prerelease (3.2.0a24)? Cheers, Sebastiaan

  in new version 3.2 Comment by sebastiaan January 2018
• Hi Agnès, It runs fine for me (though quite slowly), and it's not clear to me where this error comes from. It looks like some kind of file permission issue. @fladd does this look familiar to you? Does the experiment run if you select the legacy ba…

• Thanks for posting the stacktrace for the first error message. But could you post the full stacktrace for the second error ("Couldn't open") message as well? And could you attach the experiment file to this discussion? Right now I don't ha…

• Hi Agnès, These seem to be two separate issues, although perhaps with the same underlying cause. Could you post the full stacktrace of both error messages? You can find this in the debug window (Ctrl+D). Cheers! Sebastiaan

• Good to hear!

  in double click to get response Comment by sebastiaan January 2018
• Hi, That's a good question. coroutines execute the Prepare phase of all the items in it as the first thing of the Run phase of the coroutines item itself. In terms of temporal precision, this means that the timing within coroutines is preserved, b…

  in Do coroutine stimuli get pre-loaded? Comment by sebastiaan January 2018
• Hi Patricia, The items object did not exist in older versions of OpenSesame. Are you running an older version? If so, then I would update to the latest version (3.1) or better yet get a prerelease of 3.2. Cheers! Sebastiaan

• Hi Rotem, The easiest to way define ROIs is by first downloading the latest prerelease of OpenSesame 3.2 (which will be released as stable soon) from here: * http://osdoc.cogsci.nl/3.2 And then you can assign names to elements of a sketchpad item…

  in How to define Areas of interest in OpenSesame? Comment by sebastiaan January 2018
• Hi Beth, You've probably referred to the image as gaze_[gaze_cue].png, as in the beginner tutorial, right? If so, the variable gaze_cue is, at least in some cases, an empty string, resulting in gaze_.png. In other words, you probably have an empty …

  in Unexpected Error When Running Practice Experiment Comment by sebastiaan January 2018
• Hi Patricia, This usually happens when you have set the duration of a sketchpad to 'keypress' (which requires one keypress to advance), and then have this followed by a keyboard_response (which requires a second keypress). Is that it? See also: *…

• Hi Joanne, I'm not sure what's happening here. Could you post the entire traceback here? You can also find that in the debug window. Cheers! Sebastiaan

  in Gaze cueing - cannot run and save the experiment Comment by sebastiaan January 2018
• Hi Omer, Hmm, it's not entirely clear to me what you want to do. * The title of your discussion suggests that you want to determine the order of a loop once, and then run the loop in that same order multiple times. Do I understand that correctly? …

• Good to hear!

  in Setting duration and a key response Comment by sebastiaan January 2018
• Hi @Defne, The Link terminated error is (probably) unrelated to the memory error. Would you mind opening a new discussion for this, in which you describe the issue in more detail, including the complete stack trace (which you can find in the debug …

  in Inline_script based GUI: "error: Out of memory" Comment by sebastiaan January 2018
• Hi Matt, Without more details, it's not really possible to know what might be going on. Could you attach the experiment here? In the meanwhile, a trivial explanation might be that the microphone is muted, or that the recording level is set very lo…

  in Voice recording leads to crashing Comment by sebastiaan January 2018
• Hi Ella, You can do this with the coroutines item. This works somewhat similar to the sequence item, but allows you to run multiple other items in parallel, specifying start and end times for each of them. (Not all items support coroutines though.)…

• Hi, (Quote) OpenSesame (if you use the Windows packages) comes with its own Python environment, which is entirely separate from any other Python environments that you may have on your system. Which OpenSesame package did you install? The default Py…

  in OpenSesame crashes upon editing script Comment by sebastiaan January 2018
• Also, I will release OpenSesame 3.2 very soon! This will come with many updated libraries (I don't update libraries during a release cycle to avoid regressions), so you might luck out and find that the PyLink crash has magically disappeared. You can…

  in python crash after closing eyelink datafile Comment by sebastiaan January 2018
• Hi Jan-Bernard, I've seen this happen before. It's a bug in PyLink, and not related to the fact that you're running 32 bit libraries on a 64 bit system. (The entire Python environment is 32 bit.) There are many different versions of PyLink floati…

  in python crash after closing eyelink datafile Comment by sebastiaan January 2018
• It was indeed a character-encoding bug. It should be solved in the latest prerelease of 3.2.0 (currently 3.2.0a22). Would you mind giving this a test drive? * http://osdoc.cogsci.nl/3.2.

• Thanks for sharing that info. That sounds like a bug, and I'll see if I can reproduce it. And glad to hear that you worked it out!

  in Different computer exp not working Comment by sebastiaan January 2018
• Hi @"Matanel Weissman", I would use a simple inline_script that raises an Exception in this case. That will cause the experiment to exit. Like so: if var.acc < 80: raise Exception('Accuracy to low!') Cheers! Sebastiaan

• Ah, I see. Your csv file starts with a special unicode character (U+FEFF) called a Byte order mark (BOM). You don't see this (or you may see it as a weird character in a text editor), but it's interpreted as part of the first column name, thus leadi…

  in The loop table contains an invalid column name Comment by sebastiaan December 2017
• Hi Anita, If you can choose between a parallel and a serial port, choose the serial port—it's much more convenient, because you don't need to mess around with dlls. In addition, it's important to realize that the serial port is just a type of conn…

• A Go/ No-Go task is very simple to create, as long as you know that a response timeout is coded as the response None. Why don't you give it a try yourself first? And then if you get stuck you can of course post questions here. Cheers! Sebastiaan

• Hi, Could you attach the CSV file to this discussion? (Or a similar CSV file that triggers the same problem.) That way I can take a look at what might be wrong. Cheers, Sebastiaan
