Re: Gain and offset for physical values
Thank you so much for your quick and detailed explanation. The small value of the offset that you mention is exactly in line with what I found (a fraction of uV), so it is negligible. I just wanted to have a confirmation from you guys, because I trust your expert opinion. I occasionally use eeglab w...

Re: Gain and offset for physical values
Thank you for your quick response. I think I might have not explained correctly my question or maybe I misunderstood your answer. Bear with me, so I can be on your same page. So, in my question I was not referring to the DC voltage, which I know is present because the data are not high-passed. I was...

Gain and offset for physical values
Hello, Apologies if this question sounds a bit silly. So I have just realized that when converting the digital data into physical values I was not using the offset. I see that the offset is not mentioned in the page where the structure of the data for Biosemi is described (https://www.biosemi.com/fa...

Reading data via TCPIP
Hello, I am using the matlab code that I found on the website (TcpIpClientMatlabV1) to read EEG data. Everything looks fine with the exception for the amplitude of the data. It seems like the data that I read from TCPIP need to be calibrated. This happens even though I remove the DC component. Is th...
