Ok thanks @wjcroft. In ultracortex mark IV there are 2 earclips connected to SRB and Bias as a references. Can you explain this please?
-
Dear @wjcroft Is the GND electrode, a reference electrode as well or is something else?
-
Dear @wjcroft Thanks for your response. So the answer is YES? Is Reference electrode the CPz? Please answer me with YES or NO and if the answer is NO please tell me the electrode name-position according to international system 10-20. Also I hav…

Perfect. Thank you so much @Shirley and @wjcroft
-
Dear @wjcroft, Yes I m asking about the electrode cap. You mean if has coated electrodes, then extra care is needed right? Not sintered I cant find something else except of the following instructions: Important Notes: Electrode gel is…
-
Dear @wjcroft do you have any idea? Thanks in advance.
-
Fortunately, I replaced heads of electrodes with the Dry EEG Comb Electrodes and the problem for the time seems to be solved.
-
I checked the electrode cables and reference ear clips. Everything seems to be fine and the headset has not been used much it is very new . Unfortunately, now always electrodes 2(C4), 5(T3), 11(T5) are Railed. Please let me know how can I fix this…
-
Dear @wjcroft, Yes I changed it. I check the Impedance of channel 15 what means this "RAILED - 0.00 kOhm" ? Here is another example of channel 1 is it good 39.4 kOhm?
-
Dear @wjcroft, So if i have small value "Ohm" that means I have very good contact and if "Ohm" is big value means the contact is poor?
-
Dear @wjcroft, Thanks for your response. I don't understand how to check if the contact of the channels is ok. Can you please be more specific and give me instructions to navigate into the GUI and check the contact of every EEG. What means…
-
I don't understand what do you suggest. Please can you explain me better how can i fix the positions of the channels in the headplot step by step? Thanks a lot.
-
Dear @retiutut, Thanks for your response. What I have to put on index 9, 10, 11 in the right column from the list in the left column in OpenVibe software? Note there are all of the different channels on the left name list.
-
Great. Thank you!
-
"Is this a new Cyton you recently purchased?" Yes it is a very new purchase. Ok drivers installed and works fine! I have two more questions: 1) I have 2 earclips. I have connect the left to SRB. Where should I connect the right earclip?…

Dear @dmacd10 What kind of technique will you use? (Motor Imagery (MI), P300, SSVEP, SCP, etc.) How will you do the analysis? Are you planning to train some models? How to transfer eeg data to Unity ?
-
@retiutut ok I restart my computer and now nuget working. Thanks Is there any example of OpenBCI with Unity quickstart project based on Motor Imagery (MI)?
-
@retiutut Yes i know that is a critical first step. Why can't I install it? Do you know how can I solve this problem?
-
@retiutut As i said before, I m trying to follow the steps for BrainFlow Unity https://brainflow.readthedocs.io/en/stable/GameEngines.html#unity I dont know why I failed to install nuget.exe By run this on cmd C:\Users\Marios\Downloads>nuge…
-
Dear @wjcroft As I said previously i follow this link: https://openbci.com/community/publicly-available-eeg-datasets/ or this that is actually the same on github link: https://github.com/meagmohit/EEG-Datasets#eeg-datasets and from Motor-Imagery I …
-
Dear @wjcroft Thanks for your response. Do you have any suggested procedure to follow so that I can download the datasets?
-
Dear @wjcroft I m trying to download this datasets but failed. I fill the form and press Agree button but nothing downloaded. No email received. Any help please? http://www.bbci.de/competition/iv/#dataset1 http://www.bbci.de/competition/iv/#d…

Ok thanks a lot William. You are so helpful.
-
@wjcroft With TC26 salin electrodes pressure is required / tightening of the bands, to get reasonable signal quality. I mean salin electrodes are considered as normal wet electrodes?
-
@wjcroft Thanks a lot William. I appreciate your help very much. Apologies for the pressure in some of my questions. Its because i want to be sure if I understand right. Your idea is very nice. Many thanks for your help.
-
@wjcroft You are not sure if TC26 electrodes can connect with OpenBCI Cyton Biosensing Board? Every EEG electrode that can connect with OpenBCI's board can also work with the OpenBCI's software to get the eeg raw data?
-
@wjcroft I don't understand how the electrodes will work? Is there any board on their website that I can buy and connect the electrodes? or I need to buy the Cyton Biosensing Board (8 channels)? And how can I get the raw EEG? With the OpenBCI softw…
-
@wjcroft Thanks for your response. That is, I can use the TC26 Trainer’s Cap Bundle (https://brain-trainer.com/product/tc26-trainers-cap-bundle/) by connecting it to the Cyton + Daisy Biosensing Boards (16-Channels) (https://shop.openbci.com/coll…
-
@retiutut, @wjcroft Unfortunately I can't wait until the release of Galea. So I have to go with the EEG Electrode Cap. I was hoping for an EEG without gel or paste. Is there this option?
-
@retiutut, The question is whether it also fits with the Ultracortex Mark IV. I would prefer to use dry electrodes but I'm afraid it may not be combined with a VR headset due to its large volume and hardness. Do you think this will not be a proble…
