Re: Signal concatenation

Hello catha, the Time out setting actually triggers the end of file after all of the data have been received not after. Its name can be read as "wait for N seconds before giving up and considering the file finished". This is done because EEG data is not necessarily continuous and you do not know if ...

Re: How to trigger sound based on different EEG frequency ba

Hello Aizat89, the processing chain looks ok by design, however maybe it would be better to use a spatial filter instead of a simple channel selector (for example using a laplacian).

Re: format transformation

Hello shelldream,

where do these ns3 files come from? You could probably use EEGLAB to convert these files to gdf and then use them in openvibe, but I can not find the list of supported file formats on their web page.

Re: per target compiler and linker flags

hello smeeze,

the CMake folders will be created all over the source folder if the CMake is, for some reason, launched from the source folder.
The command

Code: Select all

find . -name CMakeFiles | grep -v local-tmp | xargs rm -fr
can help a lot.

Cheers

Re: Building OpenViBE with gcc 4.7.2

Hello xcom, the current Linux dependency installer does not compile boost, it gets it from the distribution packages. Did you do a fresh checkout?

Re: Mindwave

Hello Bruno,

we are currently in the process of obtaining a MindWave Mobile so we can address the issues. As we, unfortunately, do not have the device yet we can not look into this problem. A solution should be available in future months.

Thank you

Re: missing driver gmobilab

Hello,

is it possible that you have installed a 32bit driver on your 64bit Linux? Other issue could be an incompatibility of the driver versions.

Re: Using the VRPN Server

Hello uahmed, the vrpn generic library is only for sending data to openvibe. If you only want to get data from openvibe then this library is not necessary. You said that you got no output from C++, what are exactly the steps you did? Do you use Linux or Windows, did you link your program to the vrpn...

Re: missing driver gmobilab

Hello arakotom,

in order to compile the g.Mobilab driver you will need to have the g.Tec C API installed on the computer as well. In the case the API is installed, could you provide the log from the compilation of the acquisition server?

Re: Olimex EEG-SMT

Thank you for the test Manny,

indeed we do not have devices based on the OpenEEG in our lab so we can not vouch for any compatibility. I will add a mention to the compatible devices page for future reference.

Thank you

Hello karthiks,

what OS are you using? .lib libraries are Windows specific and cannot be used on Linux for example.

In order to help you we will need more details about your setup.
