LDA Coefficients meaning

Hi all, I am using the classifier processor box to classify simple bidimensional features... since they are in 2D I would like, given the LDA coefficients which are in the configuration file generated by the trainer, to plot the line used to divide the two classes (off-line, using an external applic...

Re: Sending External Stimulation

Hi, I checked again and the problem seems related not to the boost library versions, but to the compiler used... e.g. if I compile the external-stimulation sender example provided with the openvibe source code using minGW (that is what I commonly use when I am forced to compile stuff for windows), t...

Re: Sending External Stimulation

It works! :) 1) I downloaded the latest svn version of openvibe and compiled it 2) I recompiled my code, using the same boost library folder downloaded by the openvibe script for dependencies 3) Now the acquisition server is receiving the external stimulations from my code p.s. The precompiled versi...

Re: Sending External Stimulation

Hi, thank you very much for your answer... I have activated the External Stimulations check box and as you suggested I enabled the logging at Debug level. When the Acquisition Server stop the acquisition, it reports 0 for all the counters related to IPC... but I am sure that my code was executing th...

Sending External Stimulation

Hi, I tried to implement in my C++ code the new feature introduced in OpenVibe 0.15.0, to be able to send "External Stimulation" to the acquisition server... I successfully compiled my code using the provided example, but (while running it on the same machine), looking at the stimulations recived by...

Re: Driver gMobilabPlus under Windows

Hi, sorry for the late answer, but recently I am having huge time problems ;) ...I did not succeeded to test the driver also on Linux and it probably still have some issues for that OS since I changed it a lot to let it work also on the "multi-purpose" version of this device. Anyway I tried to let i...

Re: ssvep-scenario display problem

Hi, I have the same problem... tried to run the scenario on two different machines with different hardware and operating system and I am experiencing the same problem on both. Looking at the PSD of the recorded EEG, a clear peak in the spectrum is found only in the 15Hz frequency... all the configur...

Re: Driver gMobilabPlus under Windows

Ok, I did not forget about this driver... I am working on it and at the time I have a full working driver designed for both Linux and Windows, but tested only on windows... as soon as possible I will test it also on Linux and I will post here the source code. p.s. I changed the driver a lot... both ...

Re: Synchronization in OpenViBE

I have a problem similar to the ones discussed and I think it to be quite common, but since I do not have much experience in this field, I am asking for some suggestions/comments... We are planning some experiments where we need to show to the subjects some images/videos and we would like to acquire...

Re: Driver gMobilabPlus under Windows

Hi all, Andrea was a student working with me; he graduated some months ago... I don't think he to be still working on this driver, also beacuse we have the g.tec device here at the lab and I have not seen him recently. In case, I can go on with this work trying to merge the two drivers and do some c...

Stimulation time and date meaning

Hi, maybe this is a newbe question, since I am a newbe, but I could not find an answer: Using the "stimulation listener" I can get information about "when" a stimulation occurs in my dataset, but I get two numbers saying at which "time" and at which "date" it occurred. But in which unit? What do the...
