Re: Timing problems with gUSBampSource and P3Speller

Dear griffin.milsap, we recorded those data by an external phyton script. It is a bit courious, because the first record, was from the self written application and operator module. But i think, that is was an absolute hazard, that it worked fine. Like the timing is not allways that bad. Moreover, we...

Re: Timing problems with gUSBampSource and P3Speller

We did some more research.

Here we tested the two working versions.

I don't know why its working sometimes better (first plot of version 3.0.0) and sometimes not.

Might a notebook hard drive with 5400prm slow the system down?

Re: linear, non matrix P300

Hello, thanks for your reply. I already found the missing dynamic_cast<> that caused my unknown error. I will have a look on the StimulusPresentation Module. It looks like this is helping me solving all my problems. When i meant, that all '0' values haven't any stimulus type, i wanted to say, that i...

Hello, for a special P300 application, i need a non matrix interface for the P300 speller. i tried to change the matrix in the LoadMenu function, so that a matrix becomes [1][0][0][0][0] [0][2][0][0][0] [0][0][3][0][0] => [1][2][3][4][5] [0][0][0][4][0] [0][0][0][0][5] while all '0' targets haven't ...

Hello, i have a question about the P3Speller Interface, i used the P3Speller Code to write new applications with it. In some applications, there is "sometimes" a misstake in the interface, the letters 'Q' and 'G' sometimes look like they have a second line. I already debugged the whole thing down to...

Re: BCI2000 v3 causes problems

Hello Mr. Mellinger, i'm sorry to tell you that your solutions haven't fixed our problems. The parameter files we have loaded, run fine on other systems, also we have checked them by hand. The initially processing also seems the wrong way to fix our solutions. We have made some more expirience today...

So that if the numer of menus is just one, the Matrix gets repainted after each SelectedTarget. Therefore, i added some Code to P3SpellerTask::OnEnter() Function, Created a n...
