Dear all, I just graduated master of Biomedical Engineering. I used mean threshold and ARNN algorithms for Identification of eye commands in an EEG-controlled wheelchair. Now, I research to build BCI online and find place to do a PhD. Please share me information about scholarship or project to resea...

Hi all,
I use Active two to acquistion data, but some time it drift voltage data.
How to solve it?
I want filter data before store in BDF file? How to do this?
Thanks.

Hi all
I collect data. When I used high pass filter (no reference), the signal is good. But I don't chose high pass filter (no reference), the signal is drift.
How to solve it?
Thanks

Hi Coen and everyone !
I received data from TCP/IP, but when I decrease sample rate, the time to collect package increase. How to explain it?
Thanks.

Hi all!
I use Cheb1 in Matlab to filter data eeg. But they are not like with data filter from Active Two. What kind filter in Active Two ?
Thanks.

Thanks.
But I only downloaded ReadBDFChannel.m and ImportBDFHeader.m. I don't have funtion sopen and sread.

Thanks Coen.

Hi all!
I downloaded MatLab code to read BioSemi BDF format data files. But I don't know how to use it. Example I want read channel 1, testdata.bdf.
Thanks.

Thanks Coen.
What mean is TCP sample/channel 2 ?
I think a pakage have 192 bytes, they have 6 byte/channel (2 sample).
But when I receive data, I only receive 96 bytes/ 1 time. Is this true?
Thanks.

Hi all!
I receive data by TCP/IP. Data have 32 channels, sample rate 256. Bytes sent by server: 192 bytes. TCP samples/channel: 2. How many samples (bytes)/channel in a second I will receive?
Please help me.
Thanks.

Thanks!

Hi Coen and everyone!
I read data from server by TCP. This data have header?
I chose sample rate 256, 32 channel so byte in TCP array is 192.
But data alway negative, it isn't same on green.
Please help me.

Thanks1

Hi all!
I use matlab read data from Active Two by TCP.
I use command: data = fread(t, 2, 'int32') (t is server).
Result data= 1.0e+009 *0.9121. If a change int32 by int16, result
data = -32457. I don't know what result is true and how to check it.
Thanks.

Hi everyone.
I want to receive data from TCP?
But I don't know TCP Active Two?
Please help me?
Thanks

Thanks.

hi everyone.
I have a Ative two system. I want to build BCI online, but I don't know what to do?
Please help me?
