Re: touch mode isnot working on subject screen - 3 days ago

It seems that you programmed it as the touchscreen input, didn't you? Your device is a replacement of the mouse, not the touchscreen, so you should program it as such. The mouse input is supported only in Timing Script v2 (a.k.a., the scene framework). Use mouse_, instead of touch_. And do not forget to check on "Mouse / Key" in the .

Re: Scene5 does not terminate on fixation break before transition to Scene6 - 5 days ago

You did not provide the datafile, but I think I can tell what happened during the trial. It seems that your subject is very good at guessing the duration of the initial central fixation. You said you expected an error in Scene5 for the premature saccade. However, it does not occur there when the subject breaks the fixation very near to the end of the fixation hold, because SingleTarget does no

Re: How to draw a gray ring stimulus using MonkeyLogic Version 2? - 5 days ago

It is natural that small circles get pixelated. In addition, CircleGraphic does not do anti-aliasing, for fast graphic updates (e.g., animation). The pixelation may occur only on the control screen. Your subject screen is probably larger and you may not see it there. You do not have to use CircleGraphic. You can create the stimuli as CRC TaskObjects, which do anti-aliasing, and present them

Okay. I thought you were talking about a Wacom display model. Are you running the task in the simulation mode, by any chance?

Wacom is basically another computer, like a tablet. For the subject screen, you need a monitor controlled by your MonkeyLogic computer.

Re: Ending acquisiton of touchdata early - 12 days ago

You are right. If you display something, it cannot be moved to the alert function.

Re: Ending acquisiton of touchdata early - 12 days ago

There is no way to stop data acquisition in the middle of a trial. I do not know how you detect the entrance of the next subject, but you can put the related code in the 'trial_start' hook of the alert function, instead of the timing script, and hold the task there until the next subject is detected. Then, there is no need to worry about the data accumulation, since data is not acqui

Re: Matlab 2025a compatibility with MonkeyLogic - 17 days ago

If you update your NIMH ML to the latest version, you will at least be able to open the menu window. It is not tested though whether everything is functioning properly. I am aware of the issue and working on it, but the changes related to the UI are huge in the new release and I am busy with other things, so the final solution may take a few months.

Re: Dynamic Rotation of img/polygon - 29 days ago

You may think you explained something, but I have no idea what you are trying to do. You should explain what exactly you want to do, not how you want to do. Rather than "perform the rotation dynamically", for example, it is better to say like "present an image with 30-deg rotation in one scene and 60-deg rotation in the next scene" or "show a square rotating at 90 deg/s f

Re: Dynamic Rotation of img/polygon - 30 days ago

Sometimes an error occurs due to a simple typo. If you post only partial code, there’s not much I can tell. One clear mistake is "response = fth.Success;", since response will always be false. If this line is for reading out the scene result, it should be put after run_scene(). Adapter chains do nothing until they are executed with run_scene(). https://monkeylogic.nimh.nih.gov/docs_

Re: analogoutput randomly sends wrong waveforms - 7 weeks ago

First of all, I do not recommend calling DAQ functions directly. I cannot guarantee the future compatibility of such a usage. I do not know why you get that problem, but just wonder why it has to be complicated like that. Switching between WFs in a loop takes time and there is not so much advantage in doing so, in terms of timing accuracy. Do you have to decide on the fly which three should be

You should use your fastest drive for saving data files. Moving them to somewhere else later is up to you. There are so many ways to automatize the file copy/move, so I do not think I need to reinvent the wheel. You can use behaviorsummary, for example. https://monkeylogic.nimh.nih.gov/board/read.php?2,314,314#msg-314 function behaviorsummary(filename) movefile(filename,'D:\data&

Re: How to Present Fixation-Dependent Images Using ImageGraphic - 3 months ago

I do not see any problem in the code you showed. The issue must be caused by something else. If you are saying that you want to present multiple images sequentially during fixation within a trial, you should use ImageChanger. Running ImageGrahphic repeatedly in a loop is a bad idea, because it will introduce a time gap between images. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.htm

Re: Taking subject input via keyboard. - 3 months ago

I modified your task with a custom adapter. See the attached zip file. Before running the task, update your NIMH ML to the latest version. If you need to know exactly when the number was reported, you should record the status of the Enter key, as you do the Space bar. If you use just eventmarkers, you cannot avoid a 10-20 ms delay because sample analysis is done frame by frame in the scene fra

Re: Issues recording TTL pulses during inter-trial interval - 3 months ago

1. NIMH ML and, as far as I know, MATLAB itself are not dependent on Qt. The error is likely to come from another software that you run together. 2.
