Re: A transparent circle mask for a rectangle - 6 years ago
I don't understand who you are referring as "they" any more, but it does not make any sense that the number of coherence dots can change from frame to frame. How can the coherence level be 100%, if not all dots move in the same direction? I don't know why a mask is necessary, but I guess you are not aware that an object created earlier is shown above the others in MGL. Theby Jaewon - Questions and Answers
Re: FLIR Flea3 camera as webcam - 6 years ago
Your camera does not seem to fall into the "webcam" category. It has a way high spec and price for a webcam and, more importantly, the manufacturer's SDK should be used to control it, instead of Microsoft's common API. Some manufacturers provide a driver so that their cameras can be controlled via webcam APIs, but I guess it is not the case for your camera. As a solo prograby Jaewon - Questions and Answers

Re: A transparent circle mask for a rectangle - 6 years ago
You should read more of their papers. The density of dots is simply a parameter calculated from the number of dots. The CRT display that they initially used flashed 6670 dots/second, so they just divided it by their aperture size (400 degrees²). That is how they got the famous 16.7 dots/degree²/sec (= 6670 / 400). In their modern version of the stimuli implemented on a PC, the total number of dotby Jaewon - Questions and Answers

System requirement changes in v2.2 - 6 years ago
As some new important features, such as low latency audio in WASAPI shared mode, are available only in Windows 10, support for Window 7 will be dropped in future releases soon. This accompanies the adoption of the latest compiler, so some old MATLAB versions that do not support the new compiling tool will be excluded as well. Please consider these changes in your plan for new setups and let me knby Jaewon - News
Re: toggleobject function - 6 years ago
Please read the manual. toggleobject() is a timing script function. It is not a function that you can run on the MATLAB command window. https://monkeylogic.nimh.nih.gov/docs_CreatingTask.html#RuntimeVersion1 https://monkeylogic.nimh.nih.gov/docs_GettingStarted.html#StartingNIMHMonkeyLogicby Jaewon - Questions and Answers
Re: Task Proceeds If Meets Requirements - 6 years ago
Yes, there is. Use eyejoytrack(). Use the "function" signal type. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#eyejoytrack Since the "broken" state should be maintained, use 'holdfunc' and make the function return 1 if the IR barrier is broken and 0 otherwise. Your function needs to access get_analog_data(), so place the function at the end of yourby Jaewon - Questions and Answers
Re: best way to re-order objects on each frame - 6 years ago
Put the following line at the beginning of your timing script. If you don't have mglreverserendering in your mgl directory, please update your NIMH ML. mglreverserendering(true); % draw most recently created objects on top of othersby Jaewon - Questions and Answers
Re: best way to re-order objects on each frame - 6 years ago
You should explain what the stimulus you want to present looks like, not how you coded it. Your approach may not be appropriate for the stimulus, but, without knowing what you try to achieve by doing so, it is difficult to suggest an alternative or a workaround.by Jaewon - Questions and Answers
Re: Task Proceeds If Meets Requirements - 6 years ago
Please take a look at the get_analog_data function. You can read and analyze the IR barrier signal in the script and decide whether to proceed or not. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#get_analog_databy Jaewon - Questions and Answers
Re: Origin And Gain Calibration Method - 6 years ago
It seems that you did the procedure all right. Yes, your calibration should be done when you finish adjusting gains, but you may find the origin moved a little, if the initial gain was small and therefore did not provide enough resolution for you to set the origin precisely. Then you can just repeat the procedure a couple of times. As the gain increases, you will see better results each time.by Jaewon - Questions and Answers

Re: G-sync - 6 years ago
Posting a PDF article is not allowed, so I replaced your attachment with a pubmed link to the article. NIMH ML (more precisely MGL) is not supporting G-Sync or FreeSync currently. I am not sure if I will ever have time to support the tech, so it is up to you. This method is useful mostly for visual psychophysics experiments and you probably have to give up behavior tracking during stimulus preby Jaewon - Questions and Answers

Re: frame interval and drawing time - 6 years ago

Re: increase size of message box - 6 years ago
The function seems to work fine, so I don't understand why you say nothing is printed. You printed mostly static texts. Unless you change something in the string, you will see the same text every trial. dashboard() itself does not display anything until the screen is updated. run_scene() or idle() should be executed afterward. Also dashboard() does not clear the text of itself evenby Jaewon - Questions and Answers
Re: Deliver multiple sounds while running an ImageGraph adapter - 6 years ago
Aren't you working with Daniel? If I remember correctly, you guys already have a solution for this. What Daniel wanted was continuous sound feedback of which frequency changed according to the wheel position. That kind of control is not possible with NIMH ML alone, because resetting NI analog output takes too long.by Jaewon - Questions and Answers

Re: Solution to skipped frames - 6 years ago
The graphic card and the power supply are not critical components to boost performance in this case. From what you said, I think the speed of streaming movies from the disk may be a problem. I saw many times that conventional hard disks were not fast enough to deliver movie contents in time. I suggest trying a solid state drive.
