Apr 9, 2020 build 210 - 5 years ago

* Changes in NIMH MonkeyLogic 2 (Apr 9, 2020) + Support for low-latency voice recording via Windows Audio Session API (WASAPI) exclusive mode. - Fixed a bug that crashed MATLAB R2020a when the properties of analoginput and analogoutput objects are dumped in the command window. - Fixed an error that occurred when trying to read non-existing variables from *.mat data files.

Re: Python function to read bhv2 files - 5 years ago

Sorry. I don't have time to make an extension for another language. It may work to convert BHV2 to MAT with the bhv2mat function and read the MAT file in Python.

Re: mlplayer can't load file? - 5 years ago

They are not the same issue. The previous issue was that mlmat did not return a blank for non-existing variables. The second error is because the filepath is not a full path. I cannot rebuild the packages now, but, as a temporary solution, you can provide a full filepath to mlplayer or run it without an input argument (i.e, just type "mlplayer") and choose a file in the resulting fil

Re: How to distinguish conditions in userloop - 5 years ago

The userloop function is called every time before a trial starts. You should make it return what is necessary for the next trial and one trial only. https://monkeylogic.nimh.nih.gov/docs_CreatingTask.html#Userloop

Re: Maximum Latency - 5 years ago

Do you get 20 ms in the 2nd trial as well or even after 5-6 trials? Otherwise, I think it is okay. Again the maximum latency is usually the interval between the 1st and 2nd sample checks, which occurs at the very beginning of a trial. For the rest of the trial, the latency must be less than 0.5.ms, as indicated by your cycle rate (1/2200 = 0.45 ms).

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

I know a function handle is saved as a string, because I made it so. What I am saying is that there is no way to reconstruct the function handle from the string. There is str2func, but it doesn't check the validity of the handle and doesn't work for nested functions or if there is any externally scoped variable. As a result, the data file cannot be replayed. I would just name the mat

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.

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

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

* Changes in NIMH MonkeyLogic 2 (Mar 16, 2020) + You can adjust the transparency of overlaid webcam videos in mlplayer. - mlsetpath introduced in Feb 3, 2020 did not process relative paths correctly and therefore caused an error when reading stimuli sometimes. It is fixed now. - If 'clear all' was executed while the NIMH ML main windows was open and then a task w

Re: Multiple touch screen - 5 years ago

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.". Refer to the figure in the following link. https://monkeylogic.nimh.nih.gov/board/read.php?2,271,271#msg-271

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 - 5 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 - 5 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" - 5 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 - 5 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 - 5 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.

* Changes in NIMH MonkeyLogic 2 (Feb 3, 2020) + Now NIMH ML searches for stimulus files through a pre-determined path list so that the files may be stored anywhere in the disk. The path list can be managed in the "Set path" menu. The order of paths searched is as below. 1) The given path of the file, if the filename is a full-path string 2) Task directory, where
