Re: Maximum Latency - 5 years ago

How high is your latency? As I said above, you may be concerned about it unnecessarily. And what is your usual cycle rate?

Re: More economical way to save Stimulator waveforms - 5 years ago

Using a MAT file is exactly a way to save unique waveforms once and have a "pointer" to them. I don't think using a function handle is a good idea. There is no way to re-establish the link to the function unless you save it to a MAT file.

Download the new package and try it. I made the adapter accept a MAT file that contains waveform data. https://monkeylogic.nimh.nih.gov/docs_RuntimeFunctions.html#Stimulator

Yes. If you check on "Forced use of fallback screen", the subject screen is replaced with a window created as you specified in "Fallback screen rect."

Re: Multiple touch screen - 5 years ago

If you can touch them on Windows, you can touch them in NIMH ML. Check on "Forced use of fallback screen" and type the Windows coordinates that cover two screens, like , in "Fallback screen rect.".

Re: Maximum Latency - 5 years ago

Are you experiencing any problem due to an increased latency? I wonder why you want to do something with it, even though you do not know its meaning. The eyejoytrack function has a loop inside. At each iteration of the loop, a new analog sample is retrieved and checked. Max latency is the longest interval between two consecutive iterations and Cycle rate is the mean number of iterations per se

behaviorsummary - 5 years ago

When a task ends, NIMH ML pops up a summary window of behavioral data. If this summary is not useful, you can suppress it or create your own summary. To do so, create a "behaviorsummary.m" file in your task directory and write a function like the following. function behaviorsummary(filename) end If you want to suppress the summary window, just leave the function blank as above.

Re: Photodiode setup - 6 years ago

Please check your AI ground configuration. Signal fluctuation is not a problem of NIMH ML. It is because of improper wiring and hardware settings. https://monkeylogic.nimh.nih.gov/docs_NIMultifunctionIODevice.html#AIGroundConfiguration

Re: Photodiode setup - 6 years ago

Thanks for the figures. When you guys said the signal amplitude is low, I didn't realize how low it is. Please overwrite your mlphotodiodetuner.m with the attached file. You will be able to set the voltage range manually, if the detected range doesn't serve you well.

Re: conditions played multiple times with "random without replacement" - 6 years ago

Update your NIMH ML if your build number is earlier than 201. https://monkeylogic.nimh.nih.gov/board/read.php?1,245,245#msg-245 TrialRecord has many fields that keep trial history information. You can do some calculations from them. https://monkeylogic.nimh.nih.gov/docs_TrialRecordStructure.html If those numbers are large, the whole conditions will be just repeated after 165 trials.

Re: Photodiode setup - 6 years ago

Would you download the new package and test? Now it should autodetect the polarity from the baseline voltage. If it works okay, would you upload a screenshot? (Click the tuner window, press ALT+PrtScn, open Paint and press CTRL+V.) One shortcoming of my photodiode is that it doesn't give me clear, square-shaped responses. If yours looks good, I may want to buy one.
by Jaewon - Questions and Answers

Re: Photodiode setup - 6 years ago

I use the one built by the engineers that I am working with here, so there is no brand name or part number that I can give. I recently redesigned the tuner so that you can change the voltage threshold yourself, but haven't thought about polarity reversal. I guess I can add the feature easily. Please give me some time to make that change.

Re: Does run_scene pause the script until completion? - 6 years ago

There are a few things that I must point out. First, you should use the AllContinue adapter, instead of OrAdapter. OrAdapter checks only the Success state of fth1 and fth2, so it works if joystick is eventually acquired by either of them. However, if the subject does not respond and choice_timeout is over, neither of them can succeed and your scene falls into an infinite loop. AllContinue term

Re: Luminance Control (touchscreen or other monitor) - 6 years ago

You can change the brightness of targets by adjusting RGB values, but it is not what you are asking about, is it? If you are asking about how to make isoluminant stimuli or isoluminant colors (or that kind of question), it may not be solvable with software tools. Making isoluminant stimuli is relatively easy if you need just a few of them and use grayscale only. If you want to use isoluminant

Re: Using second Eye channel for analog arm trajectories - 6 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 c

Re: Handling adapters of different durations so the shorter one does not override the longer ones? - 6 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 stopped

Re: Handling adapters of different durations so the shorter one does not override the longer ones? - 6 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.

Re: Cap on frequency input through general inputs? - 6 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.
