(Quote) I'm not sure what you mean by this? If the problem is that the interval between trigger 1 and trigger 2 (same trial) is not the same as that between trigger 2 of one trial and trigger 1 of the next trial, then you're essentially looking for…

Hi guys, Changing the screen attribute will have no effect, because (I assume) it is used only when the window is created. But what you could do in theory is close the window, and open a new one with the desired screen keyword: from psychopy.visua…

Hi Chris, Let's walk through the command. exp is the experiment object: exp The experiment has a property items, which is a dictionary of all the items: exp.items In this dictionary, the item names are the keys, so you can get the Emotion item …

(Quote) It should be accessible now: * http://files.cogsci.nl/software/opensesame/pre-releases/ @sviter (Quote) Right, that's because Windows doesn't rename the profile folder when the username is changed. And the special characters in the profil…

Hi, The video_player hasn't been updated for a long time (it's deprecated in favor of these options, although these may not work for Mac OS). What you are running into is that the video_player doesn't support the [variable] notation. Only direct na…

Hi Bob, One thing that comes to mind is that the auto-response option may be activated on the Kubuntu system. This is a feature for testing your experiment by (sort of) emulating the participant's responses. Could that be it? (Image) Cheers! Seb…

Hi Gideon and Erez, There are two ways to send commands of this type. The first is to use Python inline code, which should be placed in an inline_script item: exp.eyelink.log("!V IAREA RECTANGLE 1 10 5 20 15 cue”) Note the difference between…

Fyi, you could try the latest pre-release package (currently 0.27.3~pre1), which contains a number of Unicode-related bug-fixes: * http://osdoc.cogsci.nl/getting-started/getting-the-latest-development-snapshot/ Among other things, this should fix …

Hi Jack, The problem is likely the same as John's: A plug-in fails to load, in this case fixation_dot. This applies to all plug-ins that use the new plug-in framework, which are currently: * joystick * fixation_dot * touch_response * notepad The …
-
(Quote) Yes, the touch_response is just a convenience plug-in that automatically classifies touches / mouse-clicks according to a grid. You can use mouse_response equally well, although you may have to recode the mouse coordinates (cursor_x and curs…

Ah, thank you for sharing these instructions! That sounds simple enough.

I don't believe Expyriment offers any control over which monitor is selected in a dual-monitor set-up, although you could ask the Expyriment developers to make sure. PsychoPy does offer this functionality, so you could consider switching to the psy…

Hi John, Indeed, there is problem with loading some of the plug-ins that are used by the Android template. Therefore the experiment doesn't start at all, and even the debug file is empty. More specifically, the touch_response and notepad plug-ins …

Hi John, Debugging output is logged to /sdcard/opensesame-debug.txt on your device, so can check there to see what went wrong. If it's not obvious, please post the debugging output here. See also: * http://osdoc.cogsci.nl/getting-started/android/…

Hi Mandy, I'm not completely sure I understand your question correctly, but you can use a variable to indicate which picture you want to show on a given trial. The easiest way to do this is to first insert one specific picture into a sketchpad. Nex…

Hi Gary and Neon, I just tried it myself, and indeed: No response from the SR Box. I was initially puzzled, but it turns out that I accidentally removed a crucial line as part of some code clean-up. I committed a fix, which should address the probl…
-
I listed this as an issue, and it should be fixed together with some other Unicode-related problems for the next maintenance release. In the meanwhile, please expose OpenSesame to as many weird characters as possible and inform us about any other pr…

Great. Consider it ignored. ;)

(Quote) The #XXXXXX notation is RGB in disguise: It's three RGB values in hexadecimal notation (so 00 - FF, which corresponds to 0 to 255 in decimal notation) in a row. To convert a tuple of three 0 - 255 values to this hexadecimal notation, you can…
-
This looks like a problem with special characters in a pathname somewhere. Could you describe exactly how OpenSesame is installed, i.e. in which folder? Do you have a username with special characters in it?
-
Hi Gary (the Swansea technician?), (Quote) In what sense did they fail to work? Did you receive an error message? (Quote) Not really, I can't see any significant changes in the srbox plug-in history for a long time. That being said, maybe there's …

Hi Ying, Recording video There are many ways to record video in Python, but it's always a little complicated. You can take a look at OpenCV. That's probably the best Python module for this kind of thing: * http://docs.opencv.org/modules/highgui/d…

Hmm, I'm afraid it's still not clear what goes wrong. If the problem still occurs, could you please provide all details that could possibly be relevant and upload the experiment somewhere? For example: * What operating system are you using? * Whic…

Hi Jakub, Basically, I don't know. It appears that the video4linux libraries occasionally triggers these segmentation faults. This didn't used to happen, back when I was developing Mantra on Ubuntu 9.10 and 10.04. But with more recent versions of U…

Hi Kim, Like Edwin says, forms offer a lot more flexibility in collecting responses. Another (trivial) solution would be to put a sticker with '10' written on it on the 0-key and a sticker with '0' written on it on the key left of the 1-key (i.e. …

Good to see you on the forum! I think we met at the APS convention, right? (Assuming that there are only a limited number of cognitive professor running MEPIS.) I think what you're running into is a bug in the version of PyQt4 (the library used for…
-
(Quote) In what sense are they blank? Is the script gone when you open the experiment in OpenSesame? Or does the experiment look fine in GUI but the forms don't appear when you actually try to run the experiment? (Quote) Do you get this error immed…
-
Hi Patrick, Edit: The error is actually due to a missing slash, as Edwin points out below. This is probably a permissions issue: You don't have write permissions in the OpenSesame folder (this is quite common). The solution would simply be to sele…

Hi Daniel, (Quote) Yes, the parallel and serial ports require entirely different approaches. Fortunately, the serial port is actually much easier to access, because it doesn't require the use of any external .dll libraries. You can simply rely on t…

ITA I'll get back to you on this!
