Emotiv EPOC
I am using the 32-bit Open Vibe 2.2.0 on my 64 bit Windows Machine, and the emotiv SDK community edition 3.3.3 to connect to Emotiv. While the connection is successful, the acquisition server stops responding after I press play. The error is the following: Screenshot (220).png Now, having read throu...

device drift is too high
I am using LSL for accepting LSL stream from Open BCI GUI. The drift is too high and keeps increasing, doesn't stop increasing, can go to 1700ms and still increases. What is the problem here? And is there a solution? I assumed LSL is good for time-synchronization, but this demonstrates otherwise. My...

display discontinuous data
I am acquiring data , epoching it , processing it (epoch again, power, average etc etc) and finally saving it. When I try to visualize the processed data from a signal display box or oscilloscope box, the box waits for a long time(possibly the time of first epoch of >1min duration) and then shows me...

python animation
I have a gauge animation indicating the power received. Ideally it should work in real-time. But, after initializing it and expecting it to change value as the program proceeds , I am stuck because the stimulations won't start until I close the figure(which was supposed to change values as the progr...

Re: Player cannot reach real time(Python)
To clarify my problem more, here is my process function: def process(self): for chunkIndex in range( len(self.input[0]) ): #print 'chunk Index' , chunkIndex if ( (len(self.store) % 30) == 1 or len(self.store)==0): self.active=0 if(type(self.input[0][chunkIndex]) == OVSignalHeader): #print 'type 1' s...

Re: Player cannot reach real time(Python)
Hi
My problem is I cannot send the instructions at the time specified because it takes 10 seconds to run the whole sequence, but chunks are coming in so before these set of commands get executed, the script would run again as chunks keep coming.

Player cannot reach real time(Python)
I have a python script that sends commands over serial protocol to an external device after certain conditions have been fulfilled. The commands are sent over a period of 10 seconds at particular times. Naturally, the python code would not stop and rather run on every chunk received, making the task...

Video in open vibe
I am creating a BCI scenario where I play a video after a certain stimulus, and close it on another stimulus, using Run Command. The video generally plays in full screen. I want to see the powers associated with different events in the video, and have the signal display. But, since the video plays i...

I have an external device that can receive instructions over serial protocol. I have a C++ code , whose functions can be used to send instructions to the device(the code encodes parameters to bits and corresponding recognizable commands and has functions to send instructions directly taking in param...

Re: Build error: Windows 10, 64 bit, Visual Studio Express 2
Before seeing this message, I installed dependencies and built again, with Python 3 in my environment variables first.
Launching through cmd works without glitches. Thanks. However, the sound player doesn't work with 64 bit windows 10, have posted it as other problem before.
