Re: Using second Eye channel for analog arm trajectories - 5 years ago
In NIMH ML, you can use as many analog input channels as you want. Eye and joystick are just special in that calibration tools and visual tracers are provided for them. NIMH ML supports two eyes and two joysticks and all of them can work independently with their own signal calibration. You won't need to script anything in most cases. Even if you use a weird, non-linear transformation to cby Jaewon - Questions and Answers
Re: Handling adapters of different durations so the shorter one does not override the longer ones? - 5 years ago
I don't think your script will work well, but it is not because of the reason you said. When run_scene() is called, the scene restarts from the beginning and so does the 5000-ms wait time. You should make the whole thing as one scene. The only condition necessary to proceed to the next scene is the acquisition of joystick movement at [4 4], so you should design your scene to be stoppedby Jaewon - Questions and Answers
Re: Handling adapters of different durations so the shorter one does not override the longer ones? - 5 years ago
Okay. Just to be sure if I understood correctly, does the subject need to move joystick with peripheral vision while holding fixation at the center? I am not sure whether you want the subject to do two responses simultaneously or sequentially and, if it has to be simultaneous, why the hold time for eye is shorter.by Jaewon - Questions and Answers

Re: Cap on frequency input through general inputs? - 5 years ago
You cannot do it, if you have only one NI board and you are using it for acquiring other signals. NI multifunction boards have only one ADC shared by all channels. Although one board may have 16 or 32 AI channels, all channels must run at the same sample frequency and the maximum possible frequency for each channel decreases as a function of the number of used channels.

It is a movie. You draw all the frames beforehand and play one by one.

Re: time problem - 5 years ago
Using movies was just one possible way to do it. I have a second thought. I think you can do it better with CurveTracer. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#CurveTracer With it, you can do something like this. The example code used to make this video is in the "task\runtime v2\11 curve trace" directory, if you download the new version. https://monkeylogic.niby Jaewon - Questions and Answers
Re: time problem - 5 years ago
That is certainly not true. You can make the task generate different movies every time. You can save them as files but also create directly from MATLAB matrices. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#MovieGraphic 1. https://monkeylogic.nimh.nih.gov/board/read.php?2,13,13#msg-13 2. https://www.ncbi.nlm.nih.gov/pubmed/11600651 See "Visual stimuli" in Methods.by Jaewon - Questions and Answers

Re: time problem - 5 years ago
1. That is normal, especially in the first trial. I made it do a test run so that the code may run faster next time. 2. You are asking your computer to do too much work. There is a cost when you switch scenes. If you want all 30 frames to be a seamless presentation, you should make the whole thing as one scene, for example, by making your stimuli as movies. 3. If you set the hold time to 2by Jaewon - Questions and Answers

Re: Error using reshape ... Product of known dimensions, 2, not divisible into total number of elements, 2x+1 - 5 years ago
I think the first error may occur if your touch screen driver somehow makes only one coordinate (either x or y) NaN, although there is no reason for it to report any NaN. Maybe there is something I can do to prevent the error. However, the second error doesn't make sense. The messages indicate you were running a trial, not loading the task, but in either case, this cannot happen. Did youby Jaewon - Questions and Answers
Re: random dot motion - 5 years ago
There are many ways to change some parameters trial by trial.

Have you looked at AudioSound, if it suits for your purpose? https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#AudioSound You don't see mglplaysound or mglpresent used in any adapter. It is because you should let NIMH ML handle stimuli to keep precise timing. You can create sounds, but you shouldn't play them yourself (unless you do it on purpose).

Re: General Input Logging - 5 years ago
The signals saved in the the data file during the simulation mode are only the kinds that you can fake with the mouse. So you probably didn't get the photodiode either. (eye is emulated with mouse and behavioral codes and strobes are outputs, which do not need emulation.) It is possible to record some real signals even during the simulation mode, but I don't do so because there is noby Jaewon - Questions and Answers
Re: Centering away from [0 0] - 5 years ago
Yes. The grid will be the same as before but just translated relatively to the new origin.by Jaewon - Questions and Answers
Re: Centering away from [0 0] - 5 years ago
The 'c' key is implemented as a hotkey like the following. hotkey('c', 'forced_eye_drift_correction([0 0],1);'); [0 0] is the coordinates of the new center (in degrees) and 1 indicates the first eye signal (2 is the second eye). So overwrite it (i.e., define it again in your timing script) with the coordinates you want.by Jaewon - Questions and Answers
Re: place polygons where touch - 5 years ago
Try the attached task. You need to enable Touchscreen in the Non-DAQ Device Settings. There is one thing you misunderstood. You can read touch_.XYData in the timing script, but you won't get any meaningful numbers. Adapters and adapter chains do something, only when they are executed by run_scene(). You need to write your own adapter and plug it in the chain, to access real-time data. Theby Jaewon - Questions and Answers
