by Saima ·Even when i am printing all channel data together in matlab i have a noisy plot like this -
noise, high impedance: electrode cap with Cyton+Daisy
by wjcroft ·What I'm asking is do you see normal eyes closed alpha with the GUI? And does that also appear with your Matlab? -
noise, high impedance: electrode cap with Cyton+Daisy
by Saima ·Do the results look normal with the GUI, but extremely low with your Matlab? In that case, suspect your Matlab DSP operations. -

noise, high impedance: electrode cap with Cyton+Daisy
by Saima ·I am using OPENBCI 21 channel cap with Cyton and daisy board. My PHD thesis is to collect data for emotion classification using random visual stimuli. I have developed a MATLAB software to separate an -
New GUI version doesn't allow LSL streaming of time series
by wjcroft ·If you read the text at the link you gave, it suggests using the Brainflow library to stream directly from the board using Matlab. So thus you avoid requiring the GUI to stream via the Networking / LS -

Data collection with LSL
by Saima ·@retiutut thank you so much for your guidance....... if i update the new version of GUI....then there is no option of time series in LSL streams and documents "https://docs.openbci.com/Software/ -
Data collection with LSL
by wjcroft ·case, the easiest approach is to filter on your Matlab side. We can file an 'issue' on the Github to have the GUI buttons repaired. But that would take much longer than just doing the filtering with -
Data collection with LSL
by wjcroft ·They recommend joining the LSL Slack and asking there. That is where the LSL experts are. Even if you have an LSL question specific to OpenBCI, that Slack should be able to point you in the right dire -

Poor data quality, plotted in EEGLAB / Matlab
by Saima ·I have plotted the OPENBCI .TXT file in EEGLAB properly, but as in my experiment i will have to collect data using LSL in matlab as i need to show the visual stimuli simultaneously. I have used the co -
Poor data quality, plotted in EEGLAB / Matlab
by Saima ·I followed Irene tutorial to open OpenBCI .txt file in MATLAB and separated its AUX and channel data as Irene did ...and it worked wonderfully .Now i will read more tutorial as i have few stimulus vid -
Poor data quality, plotted in EEGLAB / Matlab
by Saima ·The code i shared above to open OPENBCI .TXT file in matlab has been taken from "https://irenevigueguix.wordpress.com/2016/04/22/loading-openbci-datasets-in-eeglab/" tutorial. but i will loo -
Poor data quality, plotted in EEGLAB / Matlab
by wjcroft ·If the time series data plots look ok with OpenBCI_GUI, but distorted with Matlab or EEGLAB, then your import and filtering in those apps must be sub-optimal. Remember that the recording file is RAW d -
Poor data quality, plotted in EEGLAB / Matlab

Poor data quality, plotted in EEGLAB / Matlab
by retiutut ·For issues such as this, it's very important to share the code that you have written in Matlab. -
Poor data quality, plotted in EEGLAB / Matlab
by Saima ·Can any one please guide me why my data is being plotted like this as i haven't encounter that kind of EEG data plot yet. I have made all my channels "Not Railed" and impedance of channel w -
