Re: mouse_position - 5 years ago
First of all, the behavior of NIMH ML that you are talking about is perfectly normal and made it that way by design. You think that you are controlling the task with keyboard and mouse, but, in fact, the keyboard and mouse are tools for subjects to report responses with. So you are actually borrowing them from subjects. NIMH ML displays visual stimuli both on the subject and control screen soby Jaewon - Questions and Answers

Re: Origin And Gain Calibration Method - 5 years ago
Raw-signal means no calibration. Choose one of the other options. The signal never entered the central target window, because you did not set the origin. Once you press the space bar, it will come to the center of your screen. If you are not sure where the subject is looking at, just use your best guess. If the result is not satisfactory, try again multiple times. If the subject is not traiby Jaewon - Questions and Answers
Re: Task Objects, Incorrect Touches, & ToggleObject() - 5 years ago
The scene framework is neither difficult nor advanced. It is just different. There is no need to start from the runtime v1. 1. The CRC TaskObject is inherited from the original ML with the blurry edge. Use the CircleGraphic adapter of the scene framework, if you want a sharp circumference. 2. I don't get what the point of your question is. If you want to present only one stimulus, justby Jaewon - Questions and Answers
Re: problems with rewind_sound - 5 years ago
First of all, rewinding is necessary only when you play the same sound again in the same trial. So you don't need to call rewind_sound() in your first and third examples. In the first example, you hear beeps twice (or three times) because the length of your stimulus is 50 ms but you played only the ~20 ms of it in the first run. When you toggle it on again in the second (and third) run, tby Jaewon - Questions and Answers
Re: Origin And Gain Calibration Method - 5 years ago
I am not sure how you ran the calibration. Especially I don't understand these two parts: "instead of presenting the central target, I firstly moved the offset to the right" and "I then re-calibrate with less negative values in X (let's say -2)". They do not make any sense to me. Please read the manual and follow the instructions there. https://monkeylogic.nimh.nih.by Jaewon - Questions and Answers

Re: increase size of message box - 5 years ago
See If you have multiple NIMH ML copies in the MATLAB path. Sometimes MATLAB fails to delete old versions completely, when NIMH ML is installed and updated with the MATLAB installer. In that case, some functions may be called from the old versions.

Re: Simulation mode - 5 years ago
Eye #1 and Touch are both emulated by mouse. This limits the testing capability during the simulation only to the case that eye fixation and touch are required on the same position on the screen. If you need to test eye and touch at different locations, you can temporally change Eye #1 to Eye #2 or Joysticks which can be controlled by keyboard independently. https://monkeylogic.nimh.nih.gov/dby Jaewon - Questions and Answers
Re: "StimulusInfo" equivalent in new MonkeyLogic - 5 years ago
That is exactly why you should not rely on a hack to do important things. I tried to make NIMH ML flexible enough so that you don't need to hack anything. Your problem is not in reading out a value from StimulusInfo but in inserting one into it. The variable, StimulusInfo, is still there and provides extra information about TaskObjects. However, NIMH ML does not recognize a custom entry lby Jaewon - Questions and Answers

Re: A transparent circle mask for a rectangle - 5 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?

Re: FLIR Flea3 camera as webcam - 5 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 - 5 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

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
