Re: Use of mouse to control the task in Runtime version1 - 5 years ago
First of all, runtime v1 does not support mouse as a behavior tracker. If you have to use mouse, I guess you can get mouse input with mouse_position() and process it yourself. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#mouse_position Touchscreen and mouse are very different devices. Whether you use runtime v1 or v2, it is currently not possible to run touchscreen-based tasksby Jaewon - Questions and Answers

You should ask the question of NI support. If you don't know what other components of the NI-DAQmx driver are disabled/damaged, try uninstalling and reinstalling it.by Jaewon - Questions and Answers

Re: Lots of skipped frames - 5 years ago
Maybe the monitor configuration has changed due to driver update or new hardware. This is a matter between Windows and your monitors, so you just have to try different configurations, for example, by plugging the monitors to different ports, making a different monitor the main display or rearranging their relative positions.by Jaewon - Questions and Answers
Re: Eyelink integration - 5 years ago
"1 DAQ board" does not necessarily mean an NI board. It can be a sound card. To see what types of boards are available, try the following commands. >> info = daqhwinfo; >> info.InstalledAdaptors ans = 3×1 cell array {'nidaq' } {'parallel'} {'winsound'} To see if your NI board is installed correctly, run NI MAXby Jaewon - Questions and Answers
Re: Lots of skipped frames - 5 years ago
For example, is it only NIMH ML that you have changed? Is there any change in the hardware? Your latency test does not look good, so it is not the script that is a problem. Try changing the main display as suggested in the manual. https://monkeylogic.nimh.nih.gov/docs_MonitorSetup.htmlby Jaewon - Questions and Answers
Reloading device lists - 5 years ago
Unlike native Windows applications, MATLAB figures do not get "new device" notifications. After plugging USB devices (DAQ, joystick, webcam, etc.) and audio endpoint devices (speakers, headphones, mic, etc.), you need to restart NIMH ML (not the computer nor MATLA or click the refresh buttons.by Jaewon - Tips

You did not provide enough information. There hasn't been any change that may affect screen updates. Does the latency test look okay? Did you run in the simulation mode?by Jaewon - Questions and Answers

Re: Changing Trial Errors - 5 years ago
Maybe I was not clear. Changing the labels is modifying the timing script function, which will make your script incompatible with future releases. So what I meant was to use just numeric error codes in the task script and convert them to string labels of your own later. However, I got an idea how to avoid the incompatibility issue. Now you can register your own labels with the trialerror functby Jaewon - Questions and Answers
Re: Changing Trial Errors - 5 years ago
The string error codes of trialerror() are just nominal labels. There is nothing that prevents you from putting your own labels on the numeric codes. Modifying the timing script functions is not recommended, since it will make your scripts incompatible with future releases.by Jaewon - Questions and Answers

Re: Timing out task with MultiTarget & ComplementaryWindow - 5 years ago
See the example in the ComplementaryWindow manual. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#ComplementaryWindow You just need to change SingleTarget to MultiTarget in the example.

Re: Sound cards in MonkeyLogic - 5 years ago
You can play different sounds from different speakers. You need only one sound card. The number of speakers you can add is dependent on the sound card. If your card supports 5.1 channels, then you can add up to 6 speakers and, if it is a 7.1 channel one, up to 8. To send different sounds, just fill each channel with different sounds. For example, the following code will play a noise only frby Jaewon - Questions and Answers

Re: tobii sdk integration - 5 years ago

Re: Timestamps in filenames - 5 years ago
You are right about the timestamp added to the filename. The time should be determined when the run button is clicked. To make it so, add one line of code to Line 816 (or somewhere around it) of monkeylogic.m like the following.

Re: GigE Vision camera - 5 years ago
Plug them in and see if they show up in the menu. If they don't, they are not supported by NIMH ML. For cameras not supported, I do not know what initialization process is required and how long it takes. So it is entirely up to you how to control the cameras and sync timestamps. ----- See alert_function for placing the initialization code. https://monkeylogic.nimh.nih.gov/board/read.by Jaewon - Questions and Answers
Re: eventcodes sent (or read) twice - 6 years ago
It is the manual of your recording system that you should check. Find out what kind of input your recording system requires first. You shouldn't just try all strobe options. You did not mention what your recording system is. And this does not make any sense to me: "By lab legacy recommendation, I have strobes A/B wired together. "by Jaewon - Questions and Answers

Re: high refresh rate - 6 years ago
If you interpret my words as an indication that the control screen and the subject screen should have the same refresh rate, it is a misunderstanding. Although NIMH ML renders the same graphic on both screens, only the subject screen is updated in synchrony with the refresh rate. The control screen is not. Therefore, they do not need to have the same refresh rate. The reason that your currentby Jaewon - Questions and Answers

Re: draw taskobjects on control screen only - 6 years ago
MonkeyLogic Graphics Library (MGL), as well as NIMH DAQ Toolbox, is the backbone of NIMH ML and certainly able to present graphic objects on only one screen or both, by changing the device (or screen) number. However, NIMH ML is hard-coded to use both screens, so there is no way to present "TaskObjects" on the control screen only. It is up to you to call MGL functions directly to add yoby Jaewon - Questions and Answers
