display discontinuous data

Post by RadhaKumari »

I am acquiring data , epoching it , processing it (epoch again, power, average etc etc) and finally saving it. When I try to visualize the processed data from a signal display box or oscilloscope box, the box waits for a long time(possibly the time of first epoch of >1min duration) and then shows me data , in a weird manner that I cannot comprehend. I have something like this:

Code: Select all

Time:2Hz	Epoch	Fp1Alpha	Fp2Alpha	Fp1Theta	Fp2Theta	Fp1Beta	Fp2Beta	Fp1HighBeta	Fp2HighBeta	Event Id	Event Date	Event Duration

and so on....
How do I efficiently visualize it?i.e., as soon a sI play the scenario, I should be able to see it.

If you use an epoch average or something like that, the signal display is really weird that's normal. Use the continous bar. it should work. Concerning the delay, it is normal also if the first data were recorded after a certain lapse of time, it waits the first data to be displayed.
Ps : The "gain" setting in the continuous bars box is the scale of the display.
