hi, I did exactly what you explained, but since I had little problem with classification trainer I directly extracted the LDA classification coefficent value using matlab and I used those values as a configuration file. I extracted this data from matlab since we can't upload matlab in openvibe I hav...

Hello, I tried to follow the way you suggested but its not working may be i am not doing it correctly. My scenario is extracting signal from generic file reader and doing all signal processing steps (filtering, epoching ) and feature aggregator ---> classification processor output as matrix display....

Thank you for your response. I will try.

Hi everyone, Requesting help regarding classification coefficient part. I am new to this openvibe, i am sorry if my question are basic and stupid i apologies :) Before going to the online experiment with openvibe, I would like to check the result of offline recorded data which was done by using matl...

sorry, I just notices the reply. I am using the updated version of Openvibe. i need email to share the dropbox. Mean while I have another one problem. I try to record the data in the real time. I added "Generic Stream Writer " to record the real time data but i could not able to save this file. It s...

I tried all the possible option by changing the blocks and epoching of 1 sec duration with 0.5 sec interval but its not working.
I replaced csv block with gdf block then its working. The problem is with the csv block, I don't know why

Thanks & regards,

hi jussi, Thank you for your response. sure, I wanted to try the offline data recording of a task. I converted this matlab data into csv file. 1) I added the csv reader block and then a temporal filter (Butterworth Bandpass) and added a signal display block to check the output signal after the filte...
