Hi,
Before trying the impossible, I just want to check with you experts, is it possible to use 2 matlab boxes, in a a que, meaning that after one is done it's sends a stimulation to the second box and only than the second one starts the initialization followed by the process part?
Many thanks,
Yael

Re: Brain product channel Number and names
Thanks, So just to make sure the problem is in the names, meaning that if I wanted channel 6- C4 - it did record this channel and this electrode and not channel 4 (F4) like written in the Channels names. The Openvibe acquisition can't change the specification of the cap right?
Many thanks,
Yael

Brain product channel Number and names
Dear Jussi, I am using the brain product MR device with the 32 cap (BC-MR-32). According to the caps coordinates, channels 6 is C4 (for example). In the Openvibe designer I choose via the channel selector box channels (6;11-14;16;29-30) which correspond to (C4,F7,F8,T7,T8,P8,TP9,TP10) according to t...

Re: Clock frequency and nb_samples_per_buffer
Thanks, I think I know why, the Epoch in the CSV file was set to 49 in a batch instead of 50.
Thanks again,

Clock frequency and nb_samples_per_buffer
Hi,
When using clock frequency of 50Hz in the Matlab scripting box, the nb samples per buffer is 49, why is that?
Many thanks,
Yael

Re: Help with Matlab scripting
Thanks Jussi, sorry on the delay, we had many holidays and vacation time :) I managed to fix the problem by deleting this line from the code: box_in = OV_addOutputBuffer(box_in,1,start_time,end_time,matrix_data); I don't know why but it works perfectly without it. The only problem I have now is when...
