Dear dman2210. Thank you for contacting me through the Forum. Unfortunatelly, we are no longer using OpenBCI. We moved toward a different solution. However, some parts of the CYTON are still part of our system, so, if something new arises, I wil…

Dear Pirla: Thanks a million for your answer. It is open! Lot of work to be done. It will be a privilege to work with you. Let me know how to proceed. If you want, drop me a line to my email [email protected] Take care, all the best. Nelson

Yes. The design is based on TI dev board. I think the error was introduced on the PCB design due to a mistake in the .sch drawing. It is important for all the people using the CYTON to double check if the mistake is there because trying to use the …

BTW, I changed the default in the firmware. Now, default for me is SRB1 off, SRB2 off and NO BIAS. But SRB1 actually is very powerful. SRB2 seems very interesting for selecting any electrode as BIAS. In reference to hardware, I saw you have BIAS_IN …
-
Well, let's say I chain the INxN to the INx+1P in order to make a sequential Bipolar Montage. Using SRB1 instead of SRB2 I can change from Bipolar Montage to Referential Montage just changing this BIT. So using SRB1 as Reference electrode is quite i…

Hi William. Yes, this is clear. However, lets assume I want to use INxP as the electrode input while connecting all the INxN as a reference electrode. This can be accomplished disconnecting SRB2 from all INxP inputs, and connecting the Reference …

Yeap. Restarted and working like a swiss watch. Question. Per Texas Instruments, the ADS chip 1299 SRB1 pin is connects to ALL the Negative INP of the channels. Why then the GUI offers the connection of SRB1 for each channel? It seems to be a "non…

Can't post image nor file....

Thank you ! It is working now. However, I can't export the application to run in stand alone mode. See the problem:

Dear Billh. Thanks a million for sharing. I will go over the papers but I have to discuss the info with the colleagues. ICU experts have their own "wish list" for cEEG and monitoring. The goal: adapt the OpenBCI_GUI to fit with ICU doctors desires…

Dear William. It is crystal clear for me the scope of liabilities and warranties implied. Needless to say we will be in charge of running all the medical protocol tests under strict medical supervision before any further advance. No commercial u…

Dear all: I need a quite simple and reduced set of features on the GUI. I have no experience in JAVA nor Processing IDE. Is anybody interested in helping me to develop the customized GUI front end for the CYTON and maintain all the credits to O…

Dear All: In which .pde is the code if (currentBoard instanceof ADS1299SettingsBoard) { double scaler = (4.5 / (pow (2, 23) - 1) / 1.0 * 1000000.); if (((ADS1299SettingsBoard)currentBoard).getUseDynamicScaler…

Apologize for my previous question, I did not see that you already added the 0.5-15Hz option. It works happy. Question. Where are the default settings for the Hardware Configuration? I need to start with NO-BIAS, SRB2 not connected and SRB1 not c…
-
Wow, now with the BrainFlow it is a charm. Can you share the code with the extra 0.5-15Hz filter added? It looks nice and smooth. I am impressed !! Nice... Very nice indeed.
-
I see. I am a little bit confused. The GUI 5.0.1 uses the Matlab filter design or everything is done inside BrainFlow? If it uses Matlab, I need the coeficients for a Bandpass filter Butterworth 2nd order 0.5-15 Hz and I need to know where to ad…
-
Ok! Look forward to test new version. In reference to add a 0.5 to 15 Hz, any shortcut on how to implement it? All the best.
-
Dear All. Can you help me to add a 0.5 to 15 Hz filter for the GUI 5.0.1? We are running tests in the Hospital and I am overwhelmed with lot of other details and I am alone in this crusade. Any "tip" on how to implement such filter will be extrem…

The comparison is based on Argentinian units that are used in public hospitals and clinics as the gold standard. Brand name ATI. However, i will go over Dr. Frey's paper and double check the gain settings as well as filters. During my own lab t…

i am using original board bought from OpenBCI with original dongle.

Dear all: I am running comparison between OpenBCI CYTON and commercial EEG unit. The preliminary results shows that sensitivity of CYTON is very low compared to commercial unit. My question is: The A/D conversion done by ADS requires a calibrat…
-
Dear All. Hope everything is going well. In Argentina situation is not improving, so far. Let me ask: 1)the new option in OpenBCI_GUI Version 5.0.1 shows a new option STREAMING (from external). Where can I see the protocol required to use with C…
-
Thank you. Worked like a charm! All the best. Nelson
-
Thanks a million. I just checked the BrainFlow side of my problem but I need to modify the Processing sketch to allow the OpenBCI_GUI to detect my COM port even if it is NOT connected to the RFDuino, but connected to my standard USD-Serial adaptor.…

Dear William. The manual "marking" option is our neurologist requirement. The idea is to provide the recorded studies with additional information for the post processing task. Of course it is not mandatory, but since they are used to have this feat…
-
You got it! This is exactly what I was looking for. So, the mark of an external event must be done on the Cyton, I will work it out. Thanks a lot. Nelson
-
Hello William. Excellent reference. I am looking for a way that I can stamp manually on the Recorded study a mark that once I do post analysis of the EEG I can reference the particular event, not an artifact, lets say, patient closed eyes, patient…

Hi William. LSL tested OK! I just downloaded the GUI 5.0 source code to play a little bit with Processing IDE. This are my first attempt to run the GUI from inside the Processing environment. I want to set the DEFAULT configuration for Cyton with…

Hi Folks. Does the GUI version 5 supports streaming LSL ? Thanks!
-
Dear William . Thanks a lot. I was reviewing the Brainflow API. It works with WiFi shield. My problem is that I need LSL. I want to have a second monitor of LSL signals remotely under the same WiFi network. So, LSL is mandatory... I have the system …
