Is there an opportunity to build a python library to make a vrpn connection with external application in python?
Thanks

classifire Accuracy in openVibE
I build a system, gives a 88.7% test data accuracy(when building the classification model), But when I run the data on the classifier model and measure the accuracy with "classifier Accuracy measure" Box, the accuracy decreases to 40% ! Is that normal?

time based epoching and ii's relation with windowing functio
If I configure The time based epoching box, with epoch duration = 1 second and epoch interval = .25 second , then it will generate epochs of 1 second every .25th of a second, which is mean that there will be an interference between the first output and the second output element, what I mean by inter...

Re: unexpected behavioure for python code
The problem was in my python code :shock: , the dimension label does not meet the dimension size, so I edit my code as follow for jj in range(3): dimensionLabels.append( 'channel'+str(jj) ) dimensionLabels += self.signalHeader.dimensionSizes[1] *[' '] print "dimensions label = " , len(dimensionLabel...

Re: unexpected behavioure for python code
I have install and build OV 1.0.1, and run the python_sinus_oscillator.xml, the scenario run perfectly for ~ 1 second then the OV designer crashed. this is the output on the terminal after running this scenario [ INF ] At time 0.000 sec <Box algorithm::(0x00001d15, 0x000035b2) aka Sinus generator> D...

Re: unexpected behavioure for python code
I have change the signal header to make the dimesoinSize = [3, self.signalHeader.dimensionSizes[1]], but the openvibe-designer.sh crashed self.signalHeader = self.input[0].pop() outputHeader = OVSignalHeader( self.signalHeader.startTime, self.signalHeader.endTime, [3, self.signalHeader.dimensionSize...

Re: unexpected behavioure for python code
I'm sorry I was think that you mean the python code of "sinus-oscillator", I didn't know that there is an xml file. I have run this file, and it's work for a second then the openvibe-designer crashed and gives me the following message: executing script file terminate called without an active excepti...

Re: unexpected behavioure for python code
Yes, it's work,instead I have build my based on 'sinus-oscillator' code. also I have pass the variable "chunk1" as an output, and it's work. I have work hardly to see what is going on and I think that the problem is about passing this specific variable "chunk1". the size for this variable is 3-by-128.

unexpected behavioure for python code
I have write the following python code to python scripting toolbox, this code will read a matrix (or spatial filters) from a file, and multiply it with the incoming signal, but the problem is that the output will always be zeros, I have print the data before send it to the output pin of the python t...

Re: how FFT box work
I have forward the output of "fft" box to "signal display" box, which is show it as a single channel.
So what is the size of the matrix that came out from the amplitude pin, for example ,number of channels X number of frequencies sample ?

how FFT box work
If I have 14 channels, how FFT box will compute the spectrum? does it concatenate the 14 channel together ,which is give a single channel with a length of 14 times the length of EEG channel? if yes, how much is that correct? what is the problem of calculate the spectrum for each channel, which is in...

Re: how openViBE deal with real time data
So based on your words, openViBE does not really support real time application ? it may or may not support this based on the algoritm that I build.jtlindgren wrote: If you want 'realtime' processing, then you need to make the processing chain fast enough to run realtime.

how openViBE deal with real time data
lets assume the following 1. I have build a scenario which is takes 5 second to through output(process) for each data block 2. each data block contains data for 1 second . from the above, each 1 second data /signal long takes 5 second to process, which means that when we process the first block, the...

using single input to python tool box to pass all channels
I have make the following editing on the averaging signal example in python tutorial, and I apply it on 3 channels with one input to the python scripting toolbox and one output , but it's always gives me that there is one input and one output, I conclude that we have to do channel localization and p...
