Re: Problem with TMSI Refa8 on 64 bits windows 7.
Laurent, the TMSi porti32 amplifier is the same device as the Nexus32 from Mindmedia so you surely can test this one ; the Refa32 however is a different device. You should ask INRIA staff at either Nancy (cortex team) or Sophia (Athena team), they could probably check that everything is in place. Ho...

Re: SPEARS Algorithm and the iBrain
Dear Stefan, thank you for sharing your deception with the OpenViBE community. I totally agree with you on the analysis of how the press relays evolution of science. I had the same feeling about the publication of the video reconstruction stuff a few months ago (could we build up computer pictures o...

Re: Question about time in OpenVibe
Dear Anton,
if you haven't read it already, please look at A (rather long) story about time, then read Fixed Point Arithmetic on Wikipedia You'll know everything about how it works and hopefully understand why it must be this way.
Hope this helps,
Regards,
Yann

Re: Standalone application
Dear Anton, sorry for the hard dependency to GTK, this has been a long discussed choice with Vincent something like 3/4 years back from now. Providing an abstraction of such a toolkit is a huge effort and was not realistic based on the man power we had back then. Ogre is a different approach, only t...

Re: Standalone application
Dear Anton, the kernel itself relies on GTK, you can't get rid of it :) Really, have you read the blog post I pointed out ? From a standalone application (whatever app you want actually), if you want to train a classifier, just run the openvibe designer (if you use C or C++, system is a good command...

Re: Standalone application
Dear Anton,
the designer already does that, just use --no-gui flag and a well prepared Player Controller box and you're done ; hard to make it easier.

Re: data file modeeg p3 version
Dear thorn101, you should consider asking for this file at the OpenEEG mailing list ; people involved in the specs of the P3 protocol are there and /probably/ not on the OpenViBE forum :) By the way, the OpenViBE driver for ModularEEG is P2, not P3 ; I think it is backward compatible but you'd bette...

Re: How to improve designer's reaction time to gtk callback
Nicolas, just keep it simple, use a reasonably high frequency for the box (that is for instance 128 Hz which is the actual kernel frequency). Calling a processing function that does nothing most of the time will not hurt the overall performance as the kernel scheduler will always come as close as "r...

Re: Having a hand on settings interface
By the way, editing the openvibe-delayed.conf file will allow you to change the settings while the designer is running. This file is read each time you start a scenario (pressing the play button) so you don't have to restart the designer to consider new configuration token values :) Hope this helps,...

Re: Box behaving differently in different situations
For testing purpose, you can also perform a downsampling of the signal using the Downsampling box. (box still marked as unstable). The Signal Decimation box is stable and perfectly matches the needs here :) just keep in mind that you sould low pass filter before using this box to avoid aliasing. Ho...
