Reading data via TCPIP

Post by apresacc » Wed Nov 25, 2015 6:27 pm

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 there anything that I am missing?

Please, let me know.
Thank you.
Alex.

Output of the Matlab client are 32-bit signed integers with LSB = (32*256)^-1 uV = 1/8192 uV (sensor channels have a different scaling, see ActiView code).
