Re: Time control - 6 years ago
What I don't understand is the part, "... but it can only last for 5 seconds". If the target and the cursor are both at [0 0] and the tracking type is 'acquiretarget', eyejoytrack ends as soon as you run it. How could it last for 5 s? From your description, I guess this is what you tried to do. = eyejoytrack('holdtarget', target, 4, 5000); % target is atby Jaewon - Questions and Answers
Re: Time control - 6 years ago
You didn't provide enough information. You should've shown at least the values of variables, the location of the target and the initial position of the cursor. By the way, the term, 'reaction time', has a very specific meaning in psychology and neuroscience. I would use a different name, like 'response period'.by Jaewon - Questions and Answers

Your touchscreen should be multitouch-enabled and you need to configure your NIMH ML to take at least 2 simultaneous touches.by Jaewon - Questions and Answers

Re: Initial position of the cursor - 6 years ago
Create two circles (blue and green). Then, when the blue circle is chosen, turn it off and turn on the green one.by Jaewon - Questions and Answers
Re: Initial position of the cursor - 6 years ago
Have you checked the "task\runtime v1\8 customized calibration" example? For joystick, you can use JoyCal or Joy2Cal. new_origin = [3 3]; JoyCal.custom_calfunc(@translate_joy); ... ... ... function xy = translate_joy(xy) n = size(xy,1); xy = xy + repmat(new_origin,n,1); end I just wrote the above code off the top of my head, so compare it with the "8 customizby Jaewon - Questions and Answers

* Changes in NIMH MonkeyLogic 2 (Aug 6, 2019) + Digital input, like buttons, is also sampled at 1kHz and recorded to the data file during tasks written in timing script v1. This has been already supported in timing script v2. + A new adapter, Sequential, is added. See the manual for details. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#Sequential - Fixed the pby Jaewon - News
Re: Image Presentation During Saccades - 7 years ago
The attached is an example task that I made based on your description. It requires the latest NIMH ML, so please update your ML first. As you know, ImageChanger starts from the first image again, when it is used in a new scene. So the entire period in which serial image presentation is necessary should be one scene (colored in blue below). To monitor other temporal and behavioral requirementsby Jaewon - Questions and Answers
Re: Trouble downloading installer - 7 years ago
It is your web browser. It just does not know what to do with the file of that extension. When it opens an HTML page of code, just save the page as NIMH_MonkeyLogic_2.mlappinstallby Jaewon - Questions and Answers
Re: Image Presentation During Saccades - 7 years ago
It is not clear to me when the image presentation should start. Is it when the fixation to the fixation point is acquired? Initially I thought you wanted to start the images with the fixation point and keep showing them until a saccade is made to the cue, but your later description is a little confusing. It would help if you could show me your script too.by Jaewon - Questions and Answers

* Changes in NIMH MonkeyLogic 2 (Jul 31, 2019) + A problem that ML crashes on some non-English versions of Windows is fixed. + All graphic functions and GUIs are rewritten for faster performance in recent versions of MATLAB. + Now all graphic adapters supports multiple object creation via the List property and you can adjust properties of each object independently.

TaskObject - 7 years ago
* Update on Jul 7, 2020 MGL now supports the z-order property, so you can change the order of graphic objects afterward in the timing script. An object with a zero z-order (default value) is shown in the back and the one with a higher z-order is presented in front of the others that have lower z-order numbers. If the z-order of two objects are the same, the one created earlier is drawn on tby Jaewon - Tips
