Because Mathwork says so :-) If a script is a script then Matlab reparses and interprets each statement again when its executed and no optimizations are...
Hi Mario, Thank you for your clear reply. Not that i've checked if it exists, but if not: there should be a section on the wiki where this kind of threads with...
No, it is the 'window' that it doesn't like, because that's indeed also a Matlab function. Either you define window = Screen('Openwindow',...); or use a...
Hi Mario, And done. I posted your message almost verbatim (it was good quality and needed no context) in the relevant section, and made a section with some...
thanks for the info! ... as far as i can tell, the 'soda lime' is just standard glass, a substrate for a conductive layer (correct me if i'm wrong!). the guy...
Depending on the total number of trials you have, another strategy is instead of saving your full struct after each trial, save it after a given number of...
Hi, I am new to PTB3 and my question is ; Can we use any response box with PTB3 or would it have to be either one of CedrusResponseBox or PsychRTBox ? Thank...

Hi Patrick, Thats a *save*->safe strategy and sounds like a good mix of two extremes to me. One point on our merging code, if both structs your trying to merge...
I don't know about that last part. Depends on whether it's a struct of ... ans = experiment: 'Blob detection experiment' title: 'BD-3' notes: 'Preliminary...
Hi Patrick, Ah ok! Youre using a different structure for mine,t hen that concatenation trick wont work indeed (sorry, didnt check your exact code, its hard to...
Hello, I have a similar question regarding sound quality. I have implemented a script similar to the BasicSoundFeedbakDemo to introduce a latency to the...
Wow, thanks, Mario! Just tested with MBP4,1/10.5.7/Octave 3.2, and it works really fine. One observation/further difference between Matlab and Octave version ...
Apparently the imread() function of Octave recognizes that the png imagefile which defines the texture in ShepardZoomdemo is a grayscale image, although it is...
Don't get it. What is a "similar question"? The original post only refers to streaming sound output, ie., continuously. You're talking about feedback from a...
So apparently GraphicsMagick++/ImageMagick on which octave's imread is based does some clever magic there… Makes sense in principle, but unfortunately...
You can use any response box that you have drivers for. The Cedrus box and RTBox are supported by our drivers, for others you'll need to develop your own...
I am using OpenWindow to obtain the windowPtr to my main display screen. I would like the window to initialize to black because the subjects are dark-adapted. ...
Hi forum, I'm attempting to download PTB to a Macbook Pro, and keep having the problem below. Subversion installs fine, but PTB won't install, with the error...

Hello, the lab I work in has been using the CMU Button Box for over a decade now and we recently upgraded to OS X 10.4 and 10.5. Problem is, we cannot find any...
I did not find anything under Screen('Preference') settings that looked like it would avoid the initial white screen. I did find a way to reduce the intensity...
Jochen, it would probably make sense to create a new FAQ entry on the Wiki which documents notable differences between Matlab and Octave like these. thanks, ...
As an addition, the BasicSoundFeedbackDemo was written over a year ago and ok for its time, but due to a few new functions added to PsychPortAudio, one could...
Something's shot with your Subversion installation, seems some required library is missing or defective. Maybe try to uninstall and reinstall subversion. ...
Hi, I have no experience with this, but as a general comment: we'd welcome to see some code in which you try to set that trigger level. Maybe you're doing...
