to explain it a bit better... I'm trying to follow the chain... In the configuration I wrote should be like this (please tell me if I'm wrong)... The signal coming from the neuroscan arrive to the FTB and then to StimulusPresentation... now a stimulus is sent and a marker is placed in the final eeg ...

I don't understand what you are trying to do.
Do you want to control stimulus presentation from FieldTrip?

Regards,

Actually I'm not sending any event to StimulusPresentation to control it. Just sending a code to the state vector, like a trigger...

StimulusPresentation and StimulusCode

Hi there... still trying to check the triggers that StimulusPresentation puts in the StimulsCode vector... I'm using this configuration: Neuroscan.exe FieldTripBuffer.exe StimulusPresentation.exe I'm presenting a sound with the StimulusPresentation and there is the StimulusCode on the .dat final fil...

Re: states/FieldTrip ...

You can also try to modify from Fieldtrip one of the existing states in BCI2000. If this works, we can then check how to create a state from Fieldtrip. well I've almost get out... but I found a double "trigger"... The point was that I thought that FTOutputEventType was the the field to write to the...

Re: sensory stimulation

the best trigger for this ERP is the time of stimulus presentation in BCI2000, which of course is stored along with the data file in the state StimulusCode. You can load the BCI2000 data file into Matlab, or convert it into ASCII for further processing. Hi there... I'm in a quite similar situation ...

Problems with blocksize and neuroscan

Hi there, I'm quite confused about the configuration of Neuroscan: I got the params back from neurogetprams and there are 2 strange things: 1) AlignChannels = -1 2) SourceChTimeOffset = -1 Another thing. From the param file I've set the SampleBlobkSize at 40 (as should be in neuroscan). I'm using Fi...

StimulusPresentation values

Hi there, actually I'm using a custom SignalProcessing module based on FiledTripBuffer. In the example at http://www.bci2000.org/wiki/index.php/Programming_Tutorial:Working_with_the_FieldTrip_buffer the examples are based on Feedback Demo Task and the code "1" moves up, while "-1" moves down and "0"...

trigger on FieldTripBuffer

Hi there, I would like to ask you how is it possible to give back a trigger signal if I need to trigger the signal of the application module of BCI2000 if I have not to trigger something happening in the signal processing module (FTBuffer), which actually is performing other things. I'm explain bett...

Just to understand, you said that FieldtripBuffer use Matlab too. Ok... but, as is written in the introduction of the FieldTrip RT buffer (http://fcdonders.ruhosting.nl/fieldtrip/doku.php?id=fieldtrip:development:realtime:buffer) FiedTripBuffer is an application that need other applications to read ...

How to setup FieldTripBuffer?

I've tried to compile FieldTripBuffer but I get some errors. I've downloaded cygwin as they suggested but it says to me: CMake Error: The source directory "/" does not appear to contain CMakeLists.txt I've tried with Borland. Under Borland (v.6) it gives me the following errors: [C++ Error] FieldTri...

Matlab functions

Hi there, I'm new to bci2000 so please excuse me if I'm going to ask you a quite stupid question. I'm reading the tutorials to adapt some matlab algoritms to bci2000 with the matlabfilter function. The point is that there should be 4 scripts that I don't find: bci_StartRun, bci_Resting, bci_Halt and...
