Do you happen to know the frequency resolution of OpenBCI-GUI, William?
-
Hi William, I am sorry, I thought you guys collaborated together. I will definitely contact him regarding eeg-pipes.
-
Hi William, I am sorry I don't understand what it really means. Does that mean I need to change the name of the package to something else? Why would it block information being processed?
-
Thanks, William. I will take a look!
-
Thank you so much, Bill and William. I will definitely look into those you suggested (windowing and SARA). However, I am not necessarily trying to remove artifacts/eye blinks. It's just that when I call that eeg-pipes function above, the values are …
-
@wjcroft Thanks for moving the post by the way.
-
@wjcroft While the raw data plotting on eye blinks is instantaneous, OpenBCI_GUI FFT plotting is not so instantaneous which means that it slowly goes up and slowly goes down. JS FFT shows similar behavior, but not the same as OpenBCI-GUI FFT; it slo…
-
One thing I wanted to mention is that the plotting is consistent. It's just that when I blink my eyes, the amplitude stays up there for a while and then comes back down.

I am sorry about attaching the screenshots this way. I don't know how to make it show in this post.
-
Thank you very much, William! I will look into those libraries and see if they work with my project.
-
When you say DSP library, you mean dsp.js, correct?
-
Thank you so much, William and Bill. EEG-pipes has a function for that, it seems like. It's called BufferFFT() and you can select the number of bins. So, each bin is 1Hz, correct? How many bins will it provide? (even though I only need 8Hz, 9Hz, 10H…
-
Thanks, Bill. I will check this library. Will this be applicable for real-time analysis as well? I am new to BCI and I can't quite understand how I can feed certain data points to the function. Thanks, William, for the suggestion. I first used EEG-…
-
By the way, my sampling rate is 250 and I believe this is necessary for FFT.
-
Thank you so much @retitut and @Billh! I will try doing your suggestions in matlab. I was going through this forum and found out that "eeg-pipes" library in javascript provides the function to study specific band power. I might as well try this.
-
I guess I am doing something wrong. I was going through the forum and found this: https://openbci.com/forum/index.php?p=/discussion/1390/detecting-eeg-frequency-bands Here, Pete is doing exactly I would like to do, but it seems like he's doing it…

Is it possible that my electrodes are not functioning well? When I first got the device from one of my lab members, he said that it's been just sitting there for a while. The values look so random to me and I can't really understand what the values …
