Parameter files in obtaining the Mu Rhythm Paramter Exp.

Post by johntjm » 17 Mar 2011, 17:19

Dear Professors:

We are trying to use BCI2000 for 1D and 2D cursor control.

The Data system are:
EEG :GRASS Model 15 Neurodata Amplifier System
A/D: Measurement Computing USB 2537

We Configured BCI2000 as in the Chapter “Obtaining Mu Rhythm Parameters in an Initial Session” within the User Tutorial。

First Start BCI2000 by running a batch file.
The contents in the batch file are:
cd ..\prog
start operat.exe
start DASSource.exe 127.0.0.1
start ARSignalProcessing.exe 127.0.0.1
start CursorTask.exe 127.0.0.1
cd ..

In the operator module, click Config.
Then we “Click Load Parameters, and load parms/mu_tutorial/InitialMuSession.prm. Then, load parms/fragments/amplifiers/<YourAmplifier>.prm. but instead of loading parms/fragments/amplifiers/<YourAmplifier>.prm we load parms/fragments/amplifiers/GRASSplusMCUSB2537.prm instead.

Click Set Config.
Finally, Close the configuration dialog by using its close button (the button labeled "X" located on the top right corner of the window).
Then the SYS Log shows us as attached fig1

My question is:
Do I need to load both parameter configuration files InitialMuSession.prm and GRASSplusMCUSB2537.prm ?

Yes, you need to load both the general configuration file, and a specific one for your amplifier. Using a text editor, make sure that the amplifier configuration file only contains parameters for the source module, such that it doesn't interfere with the configuration of signal processing and application modules.
