• Hi, Regarding monitors; we bought a consumer high-speed camera a long time ago and this turns out to be ideal for testing monitors (and experiments for that matter). It's the Casio EX-FH25 capable of 1000Hz video (at a very low resolution). One pro…

• Hi Erwin, It's a bit hard to see what's wrong like that. Maybe my attached example can give you some insight on how to (re)run an item from an inline_script item. Best, Jarik

• Hi Erwin, I think you'll have to delete that last keyboard item. If that doesn't work; could you upload (the problematic part of) your experiment? Best, Jarik

• Hi Erwin, Do you maybe have a keyboard item or a sketchpad item with duration "keypress" after your inline item? Best, Jarik

  in optional instructions Comment by Jarik May 2017
• Hi zsc, Thanks for sharing! You could also use a loop item and one sketchpad item like in my attached example. You can reuse the timer by using a linked copy of the loop. Like I did after the AnyKey sketchpad. Are you using OpenSesame version 3.1.…

  in Timer Comment by Jarik May 2017
• clock.sleep(ms) takes milliseconds, so clock.sleep(0.01) seems really short to me. But this doesn't explain the difference between debug window and inline item... http://osdoc.cogsci.nl/3.1/manual/python/clock/

• Hi Justin Fine, That is strange. I though it's mostly the same. What code are you executing exactly? Best, Jarik

• Hi all, I run both the python 2.7 and 3.5 setups (v 3.1.6) on a clean win7 x64 test pc and had no problems. Which old version did run exactly? Are you sure you have administrator privileges when installing? Best, Jarik

  in Problems with OpenSesame installation on Win7, 64 bit Comment by Jarik April 2017
• Hi Anika, This is strange. Are you able to start OpenSesame? If yes you can click Tools >> Plug-in and extension manager which will show you the path of all plug-ins and extensions and thus the path of OpenSesame. Best, Jarik

• Hi Amanda, Other people will need to have OpenSesame to run your experiment. If you mean sharing the output, take a look at: http://osdoc.cogsci.nl/3.1/manual/logging/#reading-and-processing-data-files Best, Jarik

• Hi Jarek, You can take a look here: * http://osdoc.cogsci.nl/3.1/manual/forms/performance/ I also attached an experiment that allows you to type 'into' a sketchpad. Best, Jarik :)

• It's a guess but you might want to try putting ffmpeg in the c:\windows\system32 folder. You could also see if the old VLC plugin still works. Best, Jarik

• Hi DCube, In a post above someone reports the error message includes "ffmpeg.win32.exe" instead of "ffmpeg.exe". Maybe that helps? Best, Jarik

• An error message would be informative to help you. Also looking into the tutorials might empower you with knowledge to solve this on time. http://osdoc.cogsci.nl/3.1/tutorials/beginner/ Best, Jarik

  in Problem loading media_player_mpy item into trial sequence Comment by Jarik March 2017
• You want to delete the second sequence because that is what is causing the "size error" because in can't find the size variable in block_loop because the second sequence isn't part of the block loop. (Image) You also want to make the va…

• Hi A, You want to convert the sound from .mp3 to .ogg or .wav format. Then you can use the Run if of a sequence to either play the sound with a sampler item or not. See: *http://osdoc.cogsci.nl/3.1/tutorials/beginner/#step-4-add-images-and-sound-fi…

• The question mark is in the sketchpad when building because the image is selected at runtime. Did you try to run your experiment? Best, Jarik

  in Image script on sketch pad Comment by Jarik March 2017
• Hi Hala, You will have to use [size] like file="[size].JPG" instead of (size). Best, Jarik

  in Image script on sketch pad Comment by Jarik March 2017
• Hi Robin, (Quote) OK I understand. All items including the sampler item have a time variable which holds their onset. So assuming your sampler item is named "new_sampler" means var.time_new_sampler holds the onset time (i.e. the sound sta…
