Hi, It sounds like you want to present some images frequently than others in the same loop. Is that correct? You can do this simply by having some images appear two or five times in the loop table. So your loop table will contain duplicates. There…

Hi Chris, Without more information I cannot say what causes the error, but I would first try to see if you can open the experiment on a Windows machine. If this also fails, you could upload the experiment somewhere and post the link here so that we…

Hi Johannes, Forms can indeed be really slow, and this is particularly obvious when using the text_input widget. Improving performance is certainly on the to-do list, but it's not trivial to do so while keeping forms compatible with all back-ends a…

Hi guys, I just uploaded 0.27.4~pre2. PyGame is back to 1.9.1. Could please check if the mouse issue is resolved now? * http://osdoc.cogsci.nl/getting-started/getting-the-latest-development-snapshot/ (page has moved) * http://osdoc.cogsci.nl/getti…

Hi Lee, I suspect that the problem is that you are loading the coordinate points as str objects: # ... and load the files:image1_points = np.loadtxt(path_points1, dtype = str)image2_points = np.loadtxt(path_points2, dtype = str) This will cause c…

Hi Henrik, I imagine that this too is a result from putting the reset command in the prepare phase of a script. Could that be it? If you insert an inline_script item after the practice phase and before the experimental phase, with exp.set('credits'…

Hi, I'm afraid your question is not entirely clear. As you say, you can have a different loop for each of the three sets. In what sense doesn't this work as desired? And what do you mean by 'making a loop interactive'? Cheers! Sebastiaan

Hi Chris, A sequence always has a fixed order, but it's quite easy to mimick a randomized sequence with an inline_script. See this discussion: * http://forum.cogsci.nl/index.php?p=/discussion/144/solved-randomizing-a-sequence-of-four-blocks/p1 Ch…

Hi Heather, No, I'm afraid that the form text_input widget only supports very basic interactions. This is because it's a custom widget set that has been designed from the ground up to work on a very wide range of systems and configurations. The dow…

Hi Lee, As a first step, I would determine whether the response is really not collected at all, or whether it is collected, but not correctly classified by the script. Do you see a column called response_cue_keyboard_response in the log file, and …
-
Hi Chris, (Quote) That would be a nice addition, but no, form buttons are not animated. If you want to make the experiment feel more responsive, you could for example insert a blank sketchpad after the form. This way the participant gets immediate …

Hi Maxime, The Flytouch 7 is a regular ARM-based Android tablet, so it should run OpenSesame. I'm not sure whether anyone has tested this specific device, but it seems that it's a newer version of the EKEN M009S, which is known to work (see list). …

(Quote) Whether the display timestamp corresponds to the moment that the monitor starts a new refresh cycle (i.e. blocking) or the the moment that the display is sent to the graphics card (i.e. non-blocking) depends on the back-end. The legacy back-…
-
Hi, This error is most likely due to the use of a non-numeric value to specify the Y coordinate of your text. For example, the following line of script (in a sketchpad item) corresponds to drawing 'Some text' on the center of the screen: draw tex…
-
Hi Peter, The 'Start response interval' option has been removed, because it turned out to be confusing to many users. (People assumed that enabling this option would start the actual response collection.) The functionality is still accessible throu…
-
Hi Jarik, Thanks for spotting this one. What happens is that the plug-in always uses a Gaussian jitter, even if you select a Uniform jitter. I filed an issue on this (link). As a workaround for now, you could use an inline script to implement a uni…
-
Hi Ollie, It sounds like you would be best off using a custom form: * http://osdoc.cogsci.nl/forms/custom-forms/ For example, the script below, which should be placed in a form_base plug-in item, presents a picture and three clickable checkboxes.…
-
Hi Tilly, The script below shows how you can collect responses while two sketchpads are being presented. In general, the trick is to alternate between showing a display and polling the keyboard. The responses are stored as response1, response_time1…
-
Hi Lee, Do I understand correctly that you want to use a variable color for an element of a sketchpad? This can be done quite easily, by entering a variable name (between square brackets) into the color field of the sketchpad tab. Let's say that y…
-
Hi Boo, Looking at your experimental_sequence, I think there may be too many stimuli to be preloaded. When preloading fails, OpenSesame (or actually PsychoPy, assuming you are using the psycho back-end?) will sometimes generate the stimuli at runti…

Hi Yotam, You can open the .opensesame.tar.gz file with a tool like 7-zip, and retrieve all the files that way (unless the file is corrupted, of course). I'm not sure what is going on here. It seems that you are encountering a different error now, …
-
Hi Yotam, The error appears to be a bug related to the special characters in the pathname. If you put the experiment in a folder without special characters, you should be able to open it. Does that solve the problem for you (for now)? Cheers, Seba…

It sounds like you will need to implement some network communication. This has been discussed a few times on this forum, for example here: * http://forum.cogsci.nl/index.php?p=/discussion/369/solved-simultaneous-display-of-videos-on-two-laptops * h…

Hi Edwin, It seems to be a memory-management bug in Qt4, and not related to PyGame. You will see the 'pygame parachute' message whenever a segmentation fault occurs and PyGame is loaded, regardless of where the error comes from. (I'm not sure what …
-
Hi Henrik, (Quote) One thing that comes to mind is that the code is placed in the prepare phase of the inline_reduce script. With a Run-if statement you only prevent the the run phase from being executed, but not the prepare phase. Could that be it…

Hi Wouter, I dropped them a note a while back, but I guess it hasn't been updated. In that case you can also use the ppa, they contain the same code. Cheers! Sebastiaan

Hi Jeroen, I looked at the experiment, and the <> characters are indeed interpreted as HTML tags. What makes things a bit unpredictable is that there are carry-over effects from one string to the next (issue). The obvious solution is simply …
-
Hi Ezer, The loudness measure used here is Root Mean Square (RMS), which is non-logarithmic and in arbitrary units. To know how this translates to dB, you would need to test you set-up, because that depends on various factors, the most obvious of w…
-
Hi Jeroen, It sounds like OpenSesame tries to interpret these characters as part of HTML tags. As of 0.27, a subset of HTML tags can be used to add text formatting, as described here: * http://osdoc.cogsci.nl/usage/text-formatting/ However, the s…

That looks great man! =D>
