@wjcroft @sixian I think this also resolves https://openbci.com/forum/index.php?p=/discussion/2956/high-low-frequency-energy-in-eeg-signal#latest after reviewing the bursts in the in external spectrograms. I could also be incorrect. Glad to hear …

Hi There, It looks like you are using an old version of the GUI. You are welcome to update to GUI v5.0.4, the most stable version of the GUI, for free at https://openbci.com/downloads. Take Care, RW

@Mikael_Haji I saw someone was able to answer your question on NeuroTechX slack. GUI v5.0.4 and a few earlier versions now use filters from BrainFlow Java binding. So all you have to do is pick your language and use the BrainFlow examples. https:…

@superhenrikke I am dealing with a family emergency so I may not be able to make this quickly. This is on my to-do list.
-
I think part of the Networking widget was not sending out all of the samples when using TimeSeries and LSL. It was a very specific fix.
-
I was also wondering whether there is a quantified delay between recording and receipt of data in MATLAB that the developers would have noted, i noticed that once the signals reach the end of the GUI window they transmit into the pipeline and are pi…

Steps: * Download source code for GUI * Copy libraries to /Documents/Processing/libraries * Have the BLED112 dongle plugged into the computer * Run https://github.com/OpenBCI/OpenBCI_GUI/blob/master/Networking-Test-Kit/Serial/SerialPortListT…

We limited the list to dongles that had a specific product name. Many users would see a list of 5+ serial ports, and this made them have to scroll and search for the correct port. GUI will need to be modified to use anything besides official dongles…

Thanks for reaching out, The ADS1299 chip on the Cyton allows us to accurately check the impedance on one electrode at a time. Checking impedance involves injecting a small amount of current to a given Pin. Injecting current into more than one…
-
That error is not related to setting the board mode, it's with transcribing the data format to LSL. At this point, I may try to edit the code you have shared and then upload something that should work for you. I wanted to see if you could fix it …
-
I promise that you need the Cyton in default mode to check the Accelerometer. https://docs.openbci.com/docs/02Cyton/CytonDataFormat#firmware-version-200-fall-2016-to-now-1
-
There is a filter "on/off" button in the Networking widget. I can confirm that turning this "On" will stream filtered data over LSL when you select the TimeSeries data type. Just checked the code for v5.0.4. I think I remember debugging this earl…
-
Sorry. That's not the fix. It was kind of hard to read the error log as a paragraph. I see now that Python allows multiplying an array by a scalar. Please review the following code that helps transcribe data into the chunk format for LSL. I think…
-
You probably need a multi-modal sensor network to increase the accuracy of emotion recognition. Heart rate is the easiest metric to add using Cyton pins and modified hardware settings for a channel. You can also use the pulse sensor plugged into a C…
-
The error is likely here. data[eeg_chan] returns an array and you are multiplying an entire array by 1 number. scaled_eeg_data = data[eeg_chan]*SCALE_FACTOR_EEG scaled_aux_data = data[aux_chan]*SCALE_FACTOR_AUX
-
You need the Cyton in default mode to get values from the Accelerometer. Analog and Digital signals are not what you want.

Line 20. Is it correct to put Cyton in Analogue mode? Why? Will this send accelerometer data at the correct rate (as opposed to the reduced rate mentioned in this post) This is also incorrect. Default mode for Cyton uses Accelerometer data. …
-
Lines 58 and 59 are probably not correct.... I think.... Take a look at this python code used for testing purposes: https://github.com/OpenBCI/OpenBCI_GUI/blob/master/Networking-Test-Kit/LSL/brainflow_lsl.py I think you should be using get_exg…
-
Yes.

You are getting data from the Ganglion! This is more of a question on how to use the BrainFlow backend. This is what you need: https://brainflow.readthedocs.io/en/stable/Examples.html#python-read-write-file Take Care, RW

FYI Here is a current project in active development that OpenBCI is involved with: EEG-Notebooks (Python) https://github.com/NeuroTechX/eeg-notebooks Maybe this has a paradigm you are already interested in. Also, here is a loosely documented…
-
William is correct that it would have to be some brand/kind of "BLED112" USB device to have any chance of working.
-
If you refresh the downloads page now, it should be the correct links.
-
I apologize for the mistake with the links. The CI/CD pipeline needs to be fixed for the link generation on the downloads page. An internal ticket has been made.
-
@kimheeho If you really need this, I can help you change some code in the GUI and make a custom version for your use.
-
Before in the GUI, it would list all COM ports. But for many users there are 5+ ports on their OS, and it made it difficult for users to get connected for the first time, or they had to scroll in a Cp5 MenuList to see the correct option.
-
It's almost impossible to account for hardware that can not be tested. The GUI specifically checks for the BLED112 dongle product name from the dongle that is sold in the shop.
-
@wjcroft Can we rename this thread to something more relevant? -> "Issue running GUI 5.0.4 on Windows"
-
Yea, I think the Mac signing is fine. That's at Travis (at the moment but they don't want to respond to a request for OSS credits). Mac signing is fine. Mac OS X should only show popups associated with downloading an app from the internet instead…
