How to improve designer's reaction time to gtk callback ?

Hello, I'm creating a box which includes buttons to be used during scenario execution. What I do is changing some variables in the callback associated to the buttons, and then processClock consults these variables and do what has to be done accordingly. Thus, I may wait up to 1/(box clock frequency)...

Is it possible to have a hand on this interface, configuring several column of setting or tabs ? Thanks, Nic...

Re: stimulation listener vs/ signal display

Hi Yann, I have put an output in the acquisition server (in OpenViBEToolkit::Tools::StimulationSet::append). If I run the acquisition server alone, it gives the wright number of stimulations. But if I run a basic scenario in the designer (displaying signal and stims), the output in acquisition serve...

Re: stimulation based epoching

Hi Yann, Sorry if this was confusing, I'm going to try to make it simple :) Giving a summary of the code I'm focusing on may help : boolean CBoxAlgorithmStimulationBasedEpoching::process(void) (...) l_oEpocher.m_pEpocher->initialize(); // sets m_ui64OffsetSampleCount to 0. (...) l_oEpocher.m_pEpoche...

Re: stimulation listener vs/ signal display

Hi, I've re-checked the setStimulationSet in the driver, checked that drift correction was disabled, and I have the same trigger duplication in the stimulation listener... (see attached picture). Below is the code where this is done in the driver, including the debug output. for ( OpenViBE::uint32 i...

Hi Yann,

Yes, it's a very simple scenario, with the writer just after the acquisition client.

Re: stimulation based epoching

Hi Yann, The first stimulation comes something like 30s after the scenario's start. At that time, the signal is available for the stimulation based epoching box. The boxes configurations are : epoch duration : 0.600000 epoch offset : 0.000000 stimulation to epoch from : OVTK_StimulationId_Label_xx (...

Re: stimulation listener vs/ signal display

Hi Yann,

Oh yes, I want to trust what best fits my needs :twisted:

Here is the dump (rename the txt in ov as the forum reject .ov files).
I attach also a snapshot of the driver and listener output, which shows two times the same stimulation.

Thanks for your help !

Nicolas.

stimulation based epoching

Hello, While modifying the brain invaders, I found that the signal corresponding to the first flash was not epoched by its corresponding stimulation based epocher. Waited stimulation and signal are there, but debuging showed me that, in stimulation based epoching box, the offset sample count was not...

stimulation listener vs/ signal display

Hello, We are working on the Mitsar driver and to measure the stimulations it sends, we use both signal display and stimulation listener. The test I use sends 1 stimulation 80 and 12 stimulations 40. I can see this on the signal display, but the stimulation listener shows something like 2 stim 80 an...
