Re: Integrating Pupil Labs eye tracker via LSL - 2 days ago

This is not something you can fix with a little tweak. I may be able to develop something without actual hardware, but, at some time point, the hardware will be required for testing whether everything works. Ask the vendor if they can send me a test unit. Tobii once lent me their top-of-the-line product for a month so that I could support their hardware. Maybe this company will do the same.

Restoration of the board functions - 4 days ago

Due to a system upgrade made a couple of months ago, some functions of the board (e.g., posting new topics, creating new profiles, etc.) were disabled. Most of them are restored now, but please let me know if you find anything that does not work as expected.

* Changes in 2.0.270 (Dec 19, 2024) - OnsetDetector did not report RT due to a change made in 2.2.43. It is now working correctly. (Thanks to Chaoyi Zhang)

Re: Integrating Pupil Labs eye tracker via LSL - 4 days ago

Establishing a TCP/IP connection alone does not guarantee any functionality. The critical factor is the structure of the transmitted data, which varies by vendor. Unless your eye tracker is listed among the supported hardware (https://monkeylogic.nimh.nih.gov/docs_TCPIPEyeTracker.html), it is not possible to retrieve eye positions from the connection. To support new hardware, I would need access

Re: Assigning multiple thresholds in multiTarget - 2 months ago

There are so many ways to detect such a behavior. You need to use a little imagination. For example, you can repeat the scene until the subject touches the target.

Re: Dual Touchscreen Functionality - 2 months ago

You description is confusing. What is the difference between two separate inputs and the dual screen? Are you talking about duplicating the same screen on two monitors? Then, you should set it up in the Windows Display settings.

Re: Dual Touchscreen Functionality - 2 months ago

I am posting your email reply here so that we can continue our discussion here. ------- Thank you very much for your response, but the monitor setup manual page is just about two separate inputs, not the dual screen I am looking for, which is two monkeys can play on two different touch screens at the same time.

Re: Eventmarkers and Idle - 2 months ago

I do not understand the purpose of your state machine. TDT can store the numbers sent via digital lines and their timestamps. Why do you need to build a state machine? Eventmarkers are not sent at the same time. As I said, all assigned digital lines are used together to represent one number, so there is no way to send more than one number at a time.

by Jaewon - Questions and Answers

Re: Eventmarkers and Idle - 2 months ago

I think you misunderstood something. It appears that what the screenshot shows is the traces of single digital bits. An eventmarker is a multi-digit number, not a single bit. All assigned digital lines are used at the same time whenever an eventmarker is sent out.

Re: Understanding Skipped Frames - 2 months ago

You did not provide any information about your monitors and movies. Try a refresh rate of 60 Hz, instead of 120 Hz. The size of your movies (width & height) may be so large that your system cannot process them in time. As for preloading, see the userloop example (2 movie preloading) in the task directory of your NIMH ML installation path. It has nothing to do with skipped frames though.

Re: Assigning multiple thresholds in multiTarget - 2 months ago

To use different thresholds per target, put them in columnar order, like a n-by-1 or n-by-2 matrix. n is the number of targets. mul = MultiTarget(touch_); mul.Target = [-5 0; 0 0; 5 0]; mul.Threshold = [1; 2; 3]; % a column vector mul.WaitTime = 5000; mul.HoldTime = 500; scene = create_scene(mul); run_scene(scene);

Re: MonkeyLogic not recognizing touchscreen responses - 3 months ago

You should have told me that information first. Then, we could reach this conclusion earlier. The conclusion is that I cannot help you with this issue of yours. NIMH ML receives touch input from Windows via standard APIs. There is nothing that makes NIMH ML any different from other applications. So, you should look for the reason of malfunction in your Windows or hardware, especially when it w

Re: MonkeyLogic not recognizing touchscreen responses - 3 months ago

I cannot tell whether it was an appropriate test, since I have not seen the task code. Please try the menu as shown in the following link. When the subject screen is touched, a hand icon will appear on the corresponding position of the control screen. https://monkeylogic.nimh.nih.gov/docs_IOTest.html

Re: MonkeyLogic not recognizing touchscreen responses - 3 months ago

Re: Triggering reward directly via DAQ (not bluetooth/Arduino) - 3 months ago

It is just a matter of designing/building the pump circuit and writing the code for it. Do not touch reward_function.m or anything. See this for the DAQ setup. https://monkeylogic.nimh.nih.gov/docs_MainMenu.html#DAQSettings Then, call goodmonkey() in your timing script. It will internally call reward_function.m and send out TTL pulses for your reward pumps. https://monkeylogic.nimh.nih.go

Re: TaskObject subscript operation - 4 months ago

Assigning a TaskObject to a different variable does not create a copy of the TaskObject but another variable that points to the same TaskObject. You should create two TaskObjects of the same movie, one at (0,0) and the other at (5,0), or change the position of TaskObject(3) to (5,0) with reposition_object() before presenting it again.

Re: play many movies with transparent background and variable playposition - 4 months ago

MoreInfo and Scale are the properties of TaskObjects, but CurrentPosition is just a field of MoreInfo, not part of TaskObjects. You are supposed to use rewind_object() to change the playback position of MOV or SND. To manipulate the properties of TaskObjects, use one of the following timing script functions. reposition_object() rescale_object() rotate_object()

Re: Changing photodiode settings - 4 months ago

The built-in photodiode trigger is not that much flexible. It is toggled when toggleobject() is called in Timing Script v1 or run_scene() is called in Timing Script v2. In Timing Script v2, it can also be toggled every frame or when an eventcode is sent out within a scene, by including the PhotoDiode adapter to the scene. I guess you can try some manual method, if you really want to flash the

Re: generate_condition Leads to Conversion from Struct to Double Error - 4 months ago

I think you could figure out the cause if you opened and looked at the generated conditions file. generate_condition() does not work perfectly, but I have no intention to do anything about it. It is not part of NIMH ML and will not be included in the future versions. If you want a flexible way to select stimuli, see the userloop function. https://monkeylogic.nimh.nih.gov/docs_CreatingTask.htm

Re: Use Audiocard to drive reward pulse - 4 months ago

Re: Dot Indexing Error Led to Unrecognized Field AdjustedPPD - 5 months ago

You made a mistake (actually three of the same mistake) in your script indeed, but I am not going to tell you what it is. You are supposed to fix a problem that you created yourself.

Re: Dot Indexing Error Led to Unrecognized Field AdjustedPPD - 5 months ago

You might install multiple NIMH ML versions and have the search path messed up. Try cleaning the search path with the following commands and reinstalling the latest NIMH ML. delete(which('startup.m')) restoredefaultpath matlabrc savepath exit The stimulus size changed probably because the screen size was set differently between the config files.
