data stream from neuro signals

Hi,


at the momemt I try to write a program that reduces artefacts in a incoming data stream by substracting a given template.
the problem is that i want connect to channels and modify the data stream whenever I get an extern trigger signal.
Is it in possible to perform this operation on the DAQ card? And which function calls can be used (DAQmx driver)

i use the following hardware: DAQ-Device NI6052E PCI with BNC-2110 Terminal block


Kind regards,


Marcus Hennig

Hello Marcus,

I would suggest setting up some kind of digital channel that you pool every time and depending on the state of the line, either substract or not. To do this, you would just have to setup a digital channel and read the digital line into a case structure that would select the operation to perform.
Hope this helps...
